Answer:
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
Complete the pattern by identifying the next three terms:
10, 6, 2, −2,
Answer:
-6, -10, -14
Step-by-step explanation:
The pattern decreases by 4 each time so you keep subtracting 4 from -2 and so on to get the next three terms.
Which equation represents the line that passes through the points (-3;7) and (9,-1)
Answer:
[tex]y = - \frac{2}{3} x + 5[/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
finding the slope m of the line using the above points
[tex] m = \frac{y2 - y1}{x2 - x1} = \\ \frac{ - 1 - 7}{9 - - 3} = \frac{ - 8}{9 + 3} = - \frac{8}{12} = - \frac{2}{3} [/tex]
substitute the slope and one of the points into the y-intercept form to solve for b
[tex]y = mx + b \\ 7 = - \frac{2}{3} ( - 3) + b \\ 7 = \frac{6}{3} + b \\ 7 - 2 = b \\ b = 5[/tex]
therefore the answer to the question is
[tex]y = - \frac{2}{3} x + 5[/tex]

If the diagonal of a cube is a cm , what is the volume of the cube?
Find the slope of a line that passes through the points (-3, -1) and (2, -1)
Answer:
[tex]\frac{0}{5}[/tex]
Step-by-step explanation:
In order to find the answer to this question you need to input the values in a slope formula and solve using KCF (Keep, Change, Flip) if needed.
[tex]m = \frac{y^2-y^1}{x^2-x^1}[/tex]
[tex](-3,-1),(2,-1)[/tex]
[tex](x^1,y^1)=(-3,-1)[/tex]
[tex](x^2,y^2)=(2,-1)[/tex]
Substitute:
[tex]m=\frac{-1--1}{2--3}[/tex]
Solve using KCF:
[tex]-1+1=0[/tex]
[tex]2+3=5[/tex]
[tex]=\frac{0}{5}[/tex]
Hope this helps.

What is the value of -20=-4x-6x
Answer:
x=2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
- 20 = - 4x - 6x , that is
- 20 = - 10x ( divide both sides by - 10 )
2 = x

. Let g(x) = 3x2 + 4X – 36. What is g(2)?
Answer:
Step-by-step explanation:
The notation means that wherever you see an x on the right, you let it equal 2.
g(x) = 3x^2 + 4x - 36
x = 2
g(2) = 3*2^2 + 4*2 - 36
g(2) = 3*4 + 8 - 36
g(2) = 12 + 8 - 36
g(2) = 20 - 36
g(2) = - 16

Answer:
603
Step-by-step explanation:
First divide to get unit rate:
737/11= 67
Then multiply:
67*9= 603
Hope this helps! :)
Answer:
Scott would drive 603 miles in 9 hours
Step-by-step explanation:
First to find the rate we need to see how many miles Scott can drive per hour.
737/11=67
67/1 or 67 mph is our unit rate.
so if we want to know how many miles he can drive per 9 miles we just multiply (the unite rate by how many miles) 67 x 9, which equals, 603.
I hope I could help!
