Answer:
f(-2) = -15
Step-by-step explanation:
f(x) = 5x-5
Let x = -2
f(-2) = 5(-2) -5
= -10 -5
=-15
800 + 16x = 720 + 21x. Cancel out the 720 to get 80 + 16x = 21x. Subtract 16x from both sides to get 80 = 5x. Divide by 5 to get 16 = x, or x = 16. 16 hours. The charge is 800 + 16(16), = 720 + 21(16) which = 800 + 256 = 720 + 336 which = 1,056 = 1,056. Hope this helped!
