Answer:
m=12
Step-by-step explanation:
6m+72=144
Subtract 72
6m=72
Divide 6
m=12
What is the x-intercept of the line?
Answer:
x- incept = 14
Step-by-step explanation:
Take any two points and find the slope.
(-94 , 24) & (-74 , 18)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\ = \frac{18-24}{-74-[-94]}\\\\=\frac{18-24}{-74+94}\\\\=\frac{-6}{20}\\\\=\frac{-3}{10}\\[/tex]
(-94 , 24) and m = -3/10
Equation of the line:
[tex]y-y_{1}=m(x- x_{1})\\\\y - 24 =\frac{-3}{10}(x - [-94])\\\\y-24 =\frac{-3}{10}(x + 94)\\\\y-24=\frac{-3}{10}x + 94*\frac{-3}{10}\\\\y-24 = -0.3x- 28.2\\\\ y = -0.3x - 28.2 + 24\\\\ y = -0.3x - 4.2[/tex]
At x-intercept y = 0
0 = -0.3x - 4.2
4.2 = - 0.3x
4.2/-0.3 = x
14 = x
x- incept = 14

Suppose 5,500 dollars is placed in a saving account how much money would be in the saving account after 5 years if the compound interest semiannually at a rate of 5% per year
Answer:
FV= $7,040.46
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,500
Number of periods (n)= 5*2= 10 semesters
Interest rate (i)= 0.05/2= 0.025
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1+i)^n
FV= 5,500*(1.025^10)
FV= $7,040.46
prove algebraically that n^2 -n is never an odd number when n>1
Answer:
See Below.
Step-by-step explanation:
We want to prove that:
[tex]n^2-n[/tex]
Is never an odd number when n>1.
We will have two cases. We can prove them for each case individually.
The Even Case: n is Even:
Let n be even. Then, we can rewrite n as:
[tex]n=2k[/tex]
Where k is any positive integer.
This is because twice of any integer is even, so n must be even.
Substitute this into our expression to acquire:
[tex]=(2k)^2-(2k)[/tex]
Square:
[tex]=4k^2-2k[/tex]
4 times anything is even. 2 times anything is also even. Therefore, our expression will stay even.
The Odd Case: n is Odd:
Let n be odd. Then we can rewrite n as:
[tex]n=2k-1[/tex]
Where k is any positive integer.
This is odd because twice of any number is even, but if subtracted by 1, it yields an odd number.
We will substitute this into our expression to acquire:
[tex]=(2k-1)^2-(2k-1)[/tex]
Square:
[tex]=(4k^2-4k+1)+(-2k+1)[/tex]
Simplify:
[tex]=4k^2-6k+2[/tex]
4 times anything is even. 6 times anything is even. And anything even added to 2 will still be even.
Therefore:
[tex]n^2-n[/tex]
Will never be an odd number when n>1.
Four friends do yardwork for their neighbors over the weekend, earning $\$15$, $\$20$, $\$25$, and $\$40$, respectively. They decide to split their earnings equally among themselves. In total how much will the friend who earned $\$40$ give to the others?
Answer:
$15
Step-by-step explanation:
Let A, B, C and D represent the four friends respectively.
Given the following data;
Amount earned by A = $15
Amount earned by B = $20
Amount earned by C = $25
Amount earned by D = $40
Total amount earned = 15 + 20 + 25 + 40
Total amount earned = $100
For an equal ration, each friend should be given;
Each earnings = total amount earned/number of friends
Substituting into the equation, we have;
Each earnings = 100/4
Each earnings = $25
Hence, for D with $40, would become;
D = $40 - $25
D = $15
Therefore, D would give A $10 and give B $5.
One year ago, Lindsey deposited $250 into a savings account. Her balance is now $253. Two years ago, Jenn deposited $250 into a savings account. Her balance is now $257.50. Which account has the greater simple interest rate? Explain.
This is due at 2
Jenn's account has the greater simple interest rate
Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.
For Lindsey:
Lindsey simple interest was 1.2% annually
For Jenn:
Jenn simple interest was 1.5% annually
Therefore Jenn's account has the highest simple interest rate.
^^^^^^^^^^^^^^^^^^^^
"EamonnAdams1992"
Answer:
She has a higher interest rate
Step-by-step explanation:
Lindsay’s interest is $3 for one year. Using the formula for interest, I = prt, Lindsey’s money is earning at a rate of 1.2%. Jenn has earned $3.75 for one year. Her money is earning at a rate of 1.5%, which is a higher interest rate.

Find the equation of the line.
Use exact numbers.
Answer:
y=3/4x -2
Step-by-step explanation:
I know the last box has a plus sign in front of it but it's still -2 since the y- intercept is at -2. It's the same thing but I just wanted to make sure you knew that in the last box, you still put -2.
Sorry if what I just said above is confusing, i don't know how to explain it better...

Olivia needs 54 ticks for every 3 lollipops she eats. Complete the table using equivalent ratios. Lollipops
Answer:
36:2
90:5
Step-by-step explanation:
I got 2 because if we figure out how many licks she gets for every 1 lollipop that will help find the other numbers. When we divide 54 by 3 we get 18. For every 1 lollipop she lickes 18 times. To figure out how many lollipops for 36 I added 18 plus 18 which gives me 36. I added it twice or multiples by 2. Since I multiplied by 2 the lollipops will be 2. Since we know the rate of change which is 18. We know that for 3 lollipops the person will lick 54 times. I added 54 plus 18 two times which gave me 90. So for 90 licks the person will have 5 lollipops. I hope this helps.
What is the volume of a cylinder with a radius of 1.5 inches and a height of 19 inches? Use 3.14 for pi. Round your answer to the nearest hundredth.
Answer:
134.24 in³
Step-by-step explanation:
Use the formula for the volume of a cylinder, V = [tex]\pi[/tex]r²h
Plug in the radius, pi, and the height:
V = [tex]\pi[/tex]r²h
V = (3.14)(1.5²)(19)
V = 134.235
= 134.24 in³
So, the volume of the cylinder is 134.24 in³
Answer:
134.24 in³

Answer:
y=x+40
Step-by-step explanation:
Better?
Answer: y = x + 40 (for the sake of this problem it’s y = 1x + 40)
calculate slope using y2-y1 / x2-x1
(2, 42) (3, 43)
43-42/3-2 = 1/1 so slope is 1
plug in a point to find b
y = x + b
42 = 2 + b
b = 40
y=x+40 final answer
what is the equation of the line?
a. y= -1/2x+1/2
b. y= -2/1x+1
c. y= -1/2x+1
d. y= -2/1x+1/2
Answer:
A) y = -1/2x + 1/2
Step-by-step explanation:
Find the y-intercept(when x = 0), which is 1/2.
Find the slope: m = y2-y1 / x2-x1
I used points: (3, -1), (-3,2)
m = 2 - (-1) / -3 - 3
m = 3 / - 6
m = -1/2
plug this into the slope intercept form equation: y = mx + b
y = -1/2x + 1/2

you are playing a game you lose 4.8 points lose another 7.6 points and then win 2.5 points what is the overall change in your score?
Answer:
9.9
Step-by-step explanation:
Fists you have to choose a number, ex. 20. Then subtract 4.8 from 20 equalling 15.2, then subtract 7.2 from 15.2, which equals 7.6, then add 2.5 and get 10.1. When you have that final number you must subtract it from the starting number to find the change, 20 - 10.2 = 9.9
The perimeter of an isosceles triangle is 15.6 cm. Find the lengths of its sides, if: The base is 3 cm smaller than a leg.
Answer:
The sides of the isosceles triangle are 3.2 cm, 6.2 cm and 6.2 cm
Step-by-step explanation:
The sides of an isosceles triangle are equal in length
Let the base be x cm
Since it is 3 cm smaller than a leg, the legs will be (x + 3) cm
To find the perimeter of a triangle, we add up the sides
x + x + 3 + x + 3 = 15.6
3x + 6 = 15.6
3x = 15.6 - 6
3x = 9.6
x = 9.6/3
x = 3.2 cm
So the base is 3 + 3.2 =6.2 cm
If you walked 5 2/3miles in 2 2/3hours what is the unit walking rate in miles per hour and in hours per mile
Answer:
17/8 or 2 and 1/8 in decimal= 2.125
Step-by-step explanation:
5 2/3 Divided by 2 2/3
(5*3) + 2= 17/3
(2*3) + 2= 8/3
17/3 divided by 8/3= 17/3 * 3/8
= 17/8 or 2 1/8
The sum of two numbers is 60. The greater number is 6 more than the smaller number. Which equation can be used to solve for the smaller number?

2) x- (x + 6) = 60
3) x(x + 6) = 60
04) x(x-6) = 60
Answer:
1) x + (x + 6) = 60Step-by-step explanation:
Let the numbers be x and y
x + y = 60y = x + 6Then, substituting y:
x + (x + 6) = 60Correct option is 1)

Yeshi is making Pork fing. He has only 300g of pork
So he have to adjust the ro recipe.
500g pork
150g tomatoes
100g butter
120ml water
45g green chilli
8og onion.
a How much of each of the other ingredients
should he use to make pork fing
Answer / Step-by-step explanation:
500g - 300g = 200 {200 ÷ 500 = 0.4} ---- 300g pork
0.4 × 150g = 60g tomatoes
0.4 × 100g = 40g butter
0.4 × 120ml = 48ml water
0.4 × 45g = 18g green chilli
0.4 × 8og = 3.2og onion
