Answer:
A. 15
Step-by-step explanation:
V of a right prism which this is. Is LxWxH
So 1.5x 4x2.5=15
Y=mx+b, the b is your y-intercept so just rearrange your equation
y=(3/7)x+(2/7)
your y-intercept would be b) (2/7)
See attached picture for answer
Here is the work for this equation:
2+9-x/4 =10
11-x/4=10
11-x=40
x=29
