Answer:
$375
Step-by-step explanation:
The dryer costs: $375
The washer costs $317 ($58 less than the dryer)
375 is the correct answer
5x^2−10x−2
I hope this is what you are looking for I just added (5x^2 – 9) + (-10x + 7)
to solve for a,
f(-1) = 5
a(-1)^2 + 1 = 5
a + 1 = 5, so a=4
Hope this will help
