Okay, my prior answer got deleted for no work, apparently.
I'll re-post it though.
That word problem translates to:
Answer:

Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
The slope can be found from two points.

The two points from the graph are (1, 9) and (2, 12).
Plugging in the values and evaluating.



The slope of the line is 3.
The y-intercept of the line is where the line cross the y-axis.
The line crosses the y-axis at (0, 6).

The slope-intercept form of the line is:

Answer:
area if circle =πr²=π6²=36πmm²
Answer:
(since they're similar, set them up as a proportion to find x)
14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)
196 = 8x +16 (subtract 16 from both sides)
180 = 8x (divide both sides by 8)
x= 22.5 (is your answer, or C)
Step-by-step explanation:
Answer:
(c+3b)/8 = a
Step-by-step explanation:
c= 8a-3b
Add 3b to each side
c+3b= 8a-3b+3b
c+3b = 8a
Divide each side by 8
(c+3b)/8 = 8a/8
(c+3b)/8 = a
