b
Step-by-step explanation:
Answer:
I believe the answer is the system has one solution. Both lines have the same y-intercept. And the solution is the intersection of the 2 lines.

Answer: 74</h3>
==================================================
Work Shown:
h(x) = 7x-5
h(2) = 7(2)-5
h(2) = 14-5
h(2) = 9
f(h(2)) = f(9)
f(x) = x^2-7
f(9) = 9^2-7
f(9) = 81-7
f(9) = 74
f(h(2)) = 74
-----------
Here's a slightly alternative approach:
f(x) = x^2 - 7
f(h(x)) = ( h(x) )^2 - 7
f(h(x)) = ( 7x-5 )^2 - 7
f(h(2)) = ( 7*2-5 )^2 - 7
f(h(2)) = ( 14-5 )^2 - 7
f(h(2)) = ( 9 )^2 - 7
f(h(2)) = 81 - 7
f(h(2)) = 74
The formula for the surface area of cone is:
Surface Area of Cone = π * r * l + π * r^2 , where l = slant height
Substituting the given values:
282.74 ft^2 = 3.14 * 5 ft * l + 3.14 * (5 ft)^2
<span>l = 13 ft</span>
