3x + 8(x + 9) = -5
3x + 8x + 72 = -5
11x + 72 = -5
11x + 72 - 72 = -5 - 72
11x = -77
11x/11 = -77/11
x = -7
All you have to do for this equation is to substitute the y in the second equation with what y equals to. Then you distribute and combine like-terms.
Answer:
x = -2
Step-by-step explanation:
Step 1: Substitute h(x) for -9
-9 = 4x - 1
Step 2: Solve for <em>x</em>
-8 = 4x
x = -2
The equation used to find surface area of a sphere is A=4 pi radius sqaured
So i believe the surface area is <span>314.16. In terms of pi thats 100pi</span>
OK it could be x*3-9/6+ 5/8*5 it could be
(8, 9) will be the midpoint of the segment.
You can find this by applying the formula
(x1 + x2)/2 , (y1 + y2)/2
