O A. (f - g)(x) = 4x3 + 7x2 - 6x –
B. (f - g)(x) = 4x + 7x² + 2x + 1
c. (f - g)(x) = 4x + 7x2 - 6x + 1
O D. (f - g)(x) = 4x3 + 7x2 + 2x – 3

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

y = -1

x = 8
