-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

=

x=0.8898305 is the answer to that equation

i think the answer is b x = 1, y = 35/2

16 is the coefficient

hope this
