Answer:
8 years
Step-by-step explanation:
x years later type A and type B will have the same height
Type A = Type B: 10 + (8/12)*X = 6 + (14/12)*X
multiply 12 each side
120 + 8x = 72 + 14x
14x - 8x = 120 - 72
6x = 48
x = 8
check: A: 10 x 12 + 8 x 8 = 184
B: 6 x 12 + 14 x 8 = 184
Answer:
4
Step-by-step explanation:
Slope intercept form:
y = mx + b
Where m = slope and b = y-intercept.
By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.
So now we have:
y = mx + 1/2Next, we'll find the slope.

Plug the coordinates into the formula.

So our slope is 5/8 and the y-intercept is 1/2.
Option A is the answer.
