Answer:

Step-by-step explanation:
'x = -3', when graphed, passes through the point (-3,7) and (-3,0).
Since the line passes (-3,0), the x-intercept is -3.
(-3, 7) lies on the equation.
I have attached a picture of the graphed equation.
'x = -3' should be the correct answer.
11/12 of 7 is simply their product.

1 feet is 12 inches and there is 6 segments in one feet then in 12 feet there is 72 segments
