The answer should be -2b^{3}+8
Since the artist wants to scale his drawing down 3 times, we simply divide the area of his drawing by 3, to get 720/3=240.
The artist wants his drawing area to be 240 in^2
Hope this answered your question.
<span>Line A passes through points (5, 2) and (13, 6). Line B is parallel to Line A. Line C is perpendicular to Line B. What is the slope of Line C?
6-2 4
Line A and B both have the slope m = -------- = ------ = 1/2.
13-5 8
Line C, being perpend. to lines A and B, must have the slope m = -2 (answer)</span>

Jim did not write the correct equivalent ratio.
What is ratio?
Ratio is used to compare between two numbers of the same unit. Ratio determines how much one number is bigger as compared to other.
Suppose the ratio is a : b. a is called the antecedent and b is called the consequent.
Equivalent ratio of

Which student did not write a ratio that is equivalent to ?
Step-by-step explanation:
- Direct variations are ALWAYS linear and ALWAYS go through the origin.
Because y = kx is linear function and y = 0 when x = 0
- Inverse variations are NEVER linear and NEVER go through the origin.
Because y = k/x is not a linear function and x is never zero as we can't divide by zero.
