Answer:
18
Step-by-step explanation:
Hello,
In order to solve for x, we need to isolate the variable on one side of the equation.
To do this, we subtract 450 from both sides of the equation, and this will give you:
28.75x = 517.5
As mentioned, we need to isolate x, so we divide both sides by 28.75. This will give the following.
x = 18
Hope this helps!

Answer:
f'(-1)= 3
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)= (7-(-2))/(1-(-2))=9/3=3
Slope of the tangent line in the given point equals f' at this point.
So,
f'(-1)= 3
