Answer:
[tex]y=\frac{5}{3}x-5[/tex]
Step-by-step explanation:
Slope-intercept:
[tex]y=mx+b[/tex]
m is the slope and b is the y-intercept. We know that the line passes through the y-axis at -5, so this is the y-intercept (where x is equal to 0). Insert this into the equation:
[tex]y=mx-5[/tex]
With the given information, we can form two points:
[tex](3,0)(0,-5)[/tex]
The first one is the x-intercept and the second the y-intercept. Use these to find the slope:
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}[/tex]
Rise over run is the change in the y-axis over the change in the x-axis, otherwise known as the slope. Insert the appropriate values:
[tex](3_{x1},0_{y1})\\(0_{x2},-5_{y2})\\\\\frac{-5-0}{0-3}[/tex]
Solve:
[tex]\frac{-5-0}{0-3}=\frac{-5}{-3}[/tex]
Note that both the numerator and denominator are negatives. Two negatives make a positive, so:
[tex]\frac{5}{3}[/tex]
The slope is [tex]\frac{5}{3}[/tex]
Insert into the equation:
[tex]y=\frac{5}{3}x-5[/tex]
:Done

Find the length of the missing side.
Is x=3 a solution for the equation: 3x + 7 = 13
Why or why not ?
Answer:
No.
Step-by-step explanation:
There are two different ways to do this - solve for x in the given equation or substitute the value for x and see if you get a true statement.
3x + 7 = 13 subtract 7 from both sides
3x = 6 divide by 3 on both sides
x = 2
3(3) + 7 = 13
9 + 7 = 13
16 ≠ 13
Therefore, x = 3 is not a solution for 3x + 7 = 13.

Answer:
Step-by-step explanation:
Median: 45.5
Least value of second group: 34.7
Greatest value of third group: 63.6
The median is the middle number. This is pretty obvious to see that the middle number is 45.5.
Next, we need to see what the second group is in the first place. Do you see under the number line, those two boxes? Those are the 2nd and 3rd groups. The first box is the 2nd group. You can see that there are two numbers on the 2nd group (right above the box, on the number line). They are 34.7 and 45.5. The least value of these two is 34.7.
Similarly, the 3rd group is the other box. It has 45.5 and 63.6 on it. So the greatest value of these two is 63.6.
Hope that helped,

Write an equation for the graph below in slope-intercept form:
Answer: y<1x-2
Step-by-step explanation:
Find some coordinates on the line to write a slope intercept form equation for the line and turn it into inequality.
First we need to find the slope and the y-intercept. The y intercept is when x is 0 and as we can see it already indicates that the y intercept is -2 .
(0,-2)
(2,0) Use these points o the find the slope.
0- 2 = -2
-2 -0 = -2
-2/-2 = 1 The slope is one so the equation will be y = 1x - 2 But since this is not an inequality we have to change the equal to sign to an inequality sign.
Looking at the line, it is a dashed line so the inequality sign will be > or <
The painted side of the graph represents the solutions of the graph and that is all underneath the graph so the inequality will be y < 1x-2
What is the value of x?
Answer:
8
Step-by-step explanation:
2x + 6y = 4
Since, graph passes through (x, - 2)
Therefore, plug y = - 2 in the above equation.
2x + 6*(-2) = 4
2x - 12 = 4
2x = 12 + 4
2x = 16
x = 16/2
x = 8
Hariette would like to review the income and expenses that were actually paid last month so she can determine how much to set aside for her estimated taxes. What accounting method should Hariette choose when she runs the Profit & Loss report? Cash (basis) Accrual (basis) Modified (basis) Hybrid (basis)
Answer:
Hybrid basis
Step-by-step explanation:
There are different methods of accounting used by businesses depending on their peculiar needs. Below are the type of accounting methods:
- Cash basis is when revenues and expenses are recognised when cash is recieved or paid out.
-Accrual basis is when revenue and expenses are recognised when they are earned. For example if services are rendered to a client that will pay in a week's time, since service has already been given it is considered that the future payment has been earned.
- Modified basis combines elements of cash and accrual basis. For example considering short term assets like accounts receivable and accounts payable as cash items. Long term assets are recorded on accrual basis.
- Hybrid basis is used when cash and accrual methods are used for various expenses and tax. Mostly it is used for internal accounting purposes.
In this scenario Hariette would like to review the income and expenses that were actually paid last month. This requires a cash basis that shows actual amount recieved and paid last month. Account receivable and payable are not considered.
In setting aside money for tax she will employ accrual basis accounting. It is an expense that is estimated for future use.
So the hybrid basis is the method that will be most suitable.

Answer:
M = (-1, 0) on the x-axis
Step-by-step explanation:
You know the midpoint is the average of the coordinates of the end points:
M = (S +T)/2
M = ((-4, -3) +(0, 3))/2 = (-4+0, -3+3)/2 = (-2, 0)/2
M = (-1, 0)
The midpoint is (-1, 0). It lies on the x-axis because the y-coordinate is 0.

A bucket has 16 inches of water in it but there is a hole in the bottom. Use interval notation to write the domain and range of the function H(x) = 16 - 1.25x, where x is the time the water has been leaking for (in minutes) and is the height of the water (in inches). *
Answer: range: {0in, 16in}
domain {0min, 12.8 min}
Step-by-step explanation:
When we have a function:
f(x) = y.
The range is the set of possible values of y and the domain is the set of all the possible values of x.
In this case, our function is:
H(x) = 16 - 1.25*x
which is a linear equation, and we know that the linear equations are defined (for range and domain) in the set of all the real numbers, but this is a physical situation, so we must see at the real problem.
The bucket can not have more water than the initial amount, 16 inches, so this is the maximum in the range.
The minimum height of water that we can find in the bucket is 0 inches (so the bucket is empty) then this is the minimum of the range.
Then we can write the range as:
R: 0in ≤ y ≤ 16in. = {0in, 16in}
Now we can find the extremes of the domain by using the extremes of the range:
y = 16 = 16 - 1.25*x
0 = -1.25*x
then we have x = 0min, this will be the minimum of the domain.
Now using the minimum of the range y = 0 we have:
y = 0 = 16 - 1.25*x
1.25*x = 16
x = 16/1.25 = 12.8 mins
This is the maximum time in the domain (because after this time, there is no water in the bucket)
Then the domain is:
D: 0min ≤ x ≤ 12.8 min
Amber would like to go on the field trip this Saturday. However, she was scheduled to work 10 hours and she makes $8.50 an hour. Additionally, the field trip activity fee was $30. What is her opportunity cost to go on the field trip?
Answer:
The opportunity cost is $85.
Step-by-step explanation:
The scheduled for work = 10 hours.
Money that Amber makes by earning = $8.50 per hour.
Total money earned by Amber = 10 ×8.50 = $85
The fee of the filed trip = $30
Now we have to find the filed trip’s opportunity cost. Since we know that the opportunity cost is the amount that is left in order to get the best alternative. Therefore, if Amber goes on a field trip then he has to forgive the earning. So, the total earning $85 is the opportunity cost.
Find the distance between the two points (-4, 6) and (3,-7) Your answer
Answer: 14.76 or the square root of 218
Step-by-step explanation:
To find the distance find the change in the x values and y values then square them and add them to find their square root.
-4 -3 = -7
6 - (-7) = 13
7^2 + 13^2 = c^2
49 + 169 = c^2
218 = c ^2
c= 14.76
A business man bought a car at rs 550000 and sold it rs 533500 find his loss percentage
Answer:
Cost price (c.p) = Rs. 550000
selling price (s.p) = Rs. 533500
Loss (l) = c.p - s.p
= Rs. 550000 - Rs. 533500
= Rs. 16500
Now,
Loss percentage = Actual loss * 100%
c.p
= Rs. 16500 * 100%
Rs. 550000
= 3%
Answer:
loss%=3.09%
Step-by-step explanation:
given,s.p=550000
c.p=533500
Now,loss percent= Actual loss /c.p×100%
=16500/53500×100%

On each bonce, a ball rises to 4/5 of its previous height. To what height will it rise after the third bounce, if dropped from height of 250 cm?
Answer:
128 cm
Step-by-step explanation:
After the first bounce
height = [tex]\frac{4}{5}[/tex] × 250 = 4 × 50 = 200 cm
After the second bounce
height = [tex]\frac{4}{5}[/tex] × 200 = 4 × 40 = 160 cm
After the third bounce
height = [tex]\frac{4}{5}[/tex] × 160 = 4 × 32 = 128 cm
The ball will rise to 128 cm after the third bounce, if dropped from a height of 250 cm.
What is Multiplication?Multiplication is the process of operating a number by adding the number repeatedly to itself up to the times of the other number which is multiplied to the given number.
Mathematically, we can define this as for two numbers p and q, p × q implies that p is added to itself q times or q is added to itself p times.
Initial height = 250 cm
On each bounce, a ball rises to 4/5 of its previous height.
On first bounce,
Height = (4/5) × 250 = 4 × 50 = 200 cm
On second bounce,
Height = (4/5) × 200 = 4 × 40 = 160 cm
On third bounce,
Height = (4/5) × 160 = 4 × 32 = 128 cm
This problem can also be solved using geometric progression with the formula for nth term as (a rⁿ⁻¹) where a is the first term 250, r is the common ratio 4/5 and n is 4, implies the 4th term.
Hence the height ball rise after the third bounce is 128 cm.

The Bionic Woman gives Batman a 12 second
start in a 2 kilometre race. If the Bionic Woman
runs at 5 km/min, and Batman runs at 3 km/
min, who will win the race and by how many
seconds?
Answer:
Bionic Woman wins by 4 seconds.
Step-by-step explanation:
Given:
Speed of Batman = 3 km/min
Speed of Bionic woman = 5 km/min
Total distance = 2 km
Start given to Batman = 12 seconds
To find:
Winner of the race and by how many seconds?
Solution:
Start given to Batman = 12 second start
Let us find the Distance traveled by Batman in 12 second.
12 seconds = [tex]\frac{1}{5}[/tex] minutes
[tex]Distance = Speed \times Time[/tex]
[tex]Distance = 3 \times \frac{1}{5} = 0.6\ km[/tex]
Hence, distance left for batman to be traveled = 2 - 0.6 = 1.4 km
Time taken by Batman = [tex]\frac{1.4}{3} \times 60[/tex] seconds = 28 seconds
Distance for Bionic woman to be traveled = 2 km with 5 km/min
Time taken by Bionic Woman = [tex]\frac{2}{5}[/tex] minutes = 24 seconds
Bionic woman is taking lesser time, So the winner of the race will be Bionic woman.
She will win by 28-24 = 4 seconds
So, answer is:
Bionic Woman wins by 4 seconds.

The price for each notebook is p. The number of the
notebooks bought by Lily, Jim and Jessica is a, b and c.
Which of the following expression represents the total cost
of all the notebooks bought by the three people?
Answer: price of total notebooks = p(a+b+c) or pa+pb+pc= price of total notebooks
Step-by-step explanation:
you have to add all the number of notebooks or a b and c and then multiply it by the price of each notebook. there are multiple ways to do this but those are the ways I could think of.
if a=2, b=3 and c=6 then you have to add 2+3+6 to equal 11 then multiply 11 by the price of each notebook, say p=$4.50 your equation would be 4.50*11 which is $49.50, and that would be the total of all the notebooks. these numbers metaphorical of course, but hope that puts it into perspective.

There are only two orthodontists in a village and both wore braces until last month. Dr. Carter now has straight teeth and a clean office. Dr. Shuman now has crooked teeth and a messy office. Based only on this given information, which orthodontist should you go to if you want your teeth straightened? Explain your reasoning.
Answer:
Dr Carter
Step-by-step explanation:
I would want to visit Dr. Carter for an orthodontis appointment for multiple reasons. One, he can prove that he doesn’t do his work sloppily as his office is clean, and two, he can prove that his treatments work. since his teeth are now perfectly straight, that shows that his Braces really work, whereas Dr. Shuman’s treatments either don’t work or take a lot longer for results to appear.
