Find the Slope-intercept equation of the line which passes through (3, -4) and (-3, 8).
Answer:
y = -2x + 2
Step-by-step explanation:
8 + 4/ -6
= -2
y = -2x + b
8 = -2(-3) + b
8 = 6 + b
2 = b
check work
-4 = -2(3) + 2
-4 = -6 + 2
-4 = -4

Joe spent $45 on a new pair of tennis shoes. If
the shoes were on sale for 25% off, what was
the original price?
Answer:
Original price = $60
Step-by-step explanation:
Given:
Sales price of shoes = $45
Discount rate = 25%
Find:
Original price
Computation:
Original price = Sales price of shoes[1/(1-Discount rate)]
Original price = 45[1/(1-25%)]
Original price = 45[1/(1-0.25)]
Original price = 45[1/(0.75)]
Original price = $60

Answer:
the possible line of best fit equation is;
y = 10x + 24
Step-by-step explanation:
Here, we want to get the approximate line of best fit
Mathematically, we have the general line of best fit as
y = mx + b
where m is the slope and b is the y-intercept
By joining the given lines, we can see that the y-intercept values fall a little below 30
This means that the possible y-intercept value is 24
Now, to get the slope value, we select any two points and use the slope equation
We can have (3,50) and (6,80)
Using the slope equation;
m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10
The equation is thus;
y = 10x + 24
express y= x² + 2x + 3 in the form of y= (x-h)² + k
Given:
The equation is
[tex]y=x^2+2x+3[/tex]
To find:
The vertex form of the given equation, i.e., [tex]y=x^2+2x+3[/tex].
Solution:
We have,
[tex]y=x^2+2x+3[/tex]
It can be written as
[tex]y=(x^2+2x)+3[/tex]
Add and subtract square of half of coefficient of x, i.e., [tex]\left(\dfrac{2}{2}\right)^2=1[/tex].
[tex]y=(x^2+2x+1)-1+3[/tex]
[tex]y=(x^2+2(x)(1)+1^2)+2[/tex]
[tex]y=(x+1)^2+2[/tex] [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]
Therefore, the required form of given function is [tex]y=(x+1)^2+2[/tex].

The volume of a cone is:
[tex]V_1 = \frac 13 \pi r^2 h[/tex]
For a pyramid, the volume is:
[tex]V_2 = \frac 43 r^2h[/tex]
Rewrite as:
[tex]V_2 = 4 * \frac 13 r^2h[/tex]
Divide by 4
[tex]\frac{V_2}{4} = \frac 13 r^2h[/tex]
Substitute [tex]\frac{V_2}{4} = \frac 13 r^2h[/tex] in [tex]V_1 = \frac 13 \pi r^2 h[/tex]
So, we have:
[tex]V_1 = \frac{V_2}{4} * \pi[/tex]
This gives
[tex]V_1 = \frac{\pi}{4} V_2[/tex]
Hence, the volume of the cone is [tex]\frac{\pi}{4}[/tex] the volume of the pyramid

In this figure, ST is a line.
What is the value of x?
BTW that says 2/3x
Answer:
x=108 degrees
Step-by-step explanation:
Since ST is a straight line, it measures 180 degrees. This means that x+(2/3)x=180. The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540; which is ultimately x=108.
Answer: x=108 degrees
Step-by-step explanation:

Dan is planning an event for which the total cost cannot exceed $400. Dan plans to spend $180 on food and to hire a clown at the rate of $35 per hour. Which inequality correctly shows Dan's spending in terms of h, the number of hours that the clown can be at the party? *
Answer:
using above inequality equation, we can find the total hours in which the clown can be at the party
The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Dan is planning an event for which the total cost cannot exceed $400.
And, Dan plans to spend $180 on food and to hire a clown at the rate of $35 per hour.
Now,
Let number of hours = h
So, We can formulate;
Total spend money = $180 + $35h
Hence, The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400
Thus, The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400

The width of a box in the shape of a rectangular prism is 4 inches more than the height h . The length is the difference of 9 inches and the height. A. Write a polynomial that represents the volume of the box in terms of its height (in inches). B. The volume of the box is 180 cubic inches.
Answer:
[tex](a)[/tex] [tex]V = -H^3+ 5H^2 + 36H[/tex]
[tex](b)[/tex] [tex]Length = 5in; Width = 9in; Height = 5in[/tex] or [tex]Length = 3in; Width = 10in; Height = 6in[/tex]
Step-by-step explanation:
Let:
[tex]W=Width; L = Length; H = Height[/tex]
Given
[tex]W = 4 + H[/tex]
[tex]L = 9 - H[/tex]
Solving (a): The polynomial for the volume in terms of height
Volume (V) is calculated using:
[tex]V = L * W * H[/tex]
[tex]V = (9 - H) * (4 + H) * H[/tex]
Expand
[tex]V = (9 - H) * (4H + H^2)[/tex]
Open brackets
[tex]V = 36H + 9H^2 - 4H^2 - H^3[/tex]
[tex]V = 36H + 5H^2 - H^3[/tex]
Rewrite as:
[tex]V = -H^3+ 5H^2 + 36H[/tex]
Solving (b): The dimensions when Volume = 180
Substitute 180 for V in: [tex]V = -H^3+ 5H^2 + 36H[/tex]
[tex]180 = -H^3+ 5H^2 + 36H[/tex]
Rewrite as:
[tex]H^3 - 5H^2 - 36H + 180 = 0[/tex]
Factorize:
[tex]H^2(H - 5) - 36(H - 5) = 0[/tex]
[tex](H^2 - 36)(H - 5) = 0[/tex]
Express [tex]H^2 - 36[/tex] as difference of two squares
[tex](H - 6)(H + 6)(H - 5) =0[/tex]
This gives:
[tex]H - 6 =0==> H = 6[/tex]
[tex]H + 6 =0==> H = -6[/tex]
[tex]H - 5 =0==> H = 5[/tex]
Since the height can not be negative, then H = 5 or H = 6
Recall that:
[tex]W = 4 + H[/tex]
[tex]L = 9 - H[/tex]
When H = 5
[tex]W = 4 + 5 = 9[/tex]
[tex]L = 9 - 5 = 4[/tex]
When H = 6
[tex]W = 4 + 6 = 10[/tex]
[tex]L = 9 - 6 = 3[/tex]
Hence, the dimensions of the box are:
[tex]Length = 5in; Width = 9in; Height = 5in[/tex]
or
[tex]Length = 3in; Width = 10in; Height = 6in[/tex]
The volume of the box is given by -h³ + 5h² + 36h
Volume
Volume is the amount of space occupied by a three dimensional object. The volume (V) of a box is given by:
V = length * width * height
Let h represent the the height, hence width = h + 4, length = (9 - h)
V = h(h + 4)(9 - h) = h(5h -h² + 36) = -h³ + 5h² + 36h
For a volume of 180 in³:
180 = -h³ + 5h² + 36h
h = 5 or 6.
The volume of the box is given by -h³ + 5h² + 36h

A family has two cars. The first car gets 25 miles per gallon and the second car gets 15 miles per gallon. In a week the two cars went 725 miles and consumed 35 gallons of gas. How much gas did each car use?
Answer:20 and 15 gallons
Step-by-step explanation:
Given
The first car gets 25 miles per gallon
The second car gets 15 miles per gallon
Two cars consumed 35 Gallons
they went for 725 miles in total
suppose the first car consumes x gallons
so, the second car consumes 35-x gallons of gas
We can write
[tex]\Rightarrow 25x+15(35-x)=725\\\Rightarrow 25x-10x=725-525\\\Rightarrow 10x=200\\\Rightarrow x=20[/tex]

[tex]\cos 35^{\circ}=\frac{5}{c},\\c=\boxed{\frac{5}{\cos 35^{\circ}}}[/tex].
The value of c in the right triangle ABC is 5 / cos 35°
Right triangle:
Right triangle has one of its sides as 90 degrees. The sides of a right triangle can be found using trigonometric ratios as follows;
cos 35 = adjacent / hypotenuse
where
adjacent side = 5 inches
c = hypotenuse
Therefore,
cos 35° = 5 / c
cross multiply
c cos 35° = 5
divide both sides by cos 35°
c = 5 / cos 35°
