Solve for f. -11f = 7(1 - 2f) + 5

F = 4

Step-by-step explanation:

−11f=7−14f+5

−11f=−14f+12

−11f+14f=12

3f=12

f=

3

12

f=4

f=  

23/14

=1.643

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-11-(7*(1-2*f)+5)=0

-11 -  (7 • (1 - 2f) +  5)  = 0

14f - 23  = 0

3.1      Solve  :    14f-23 = 0  

Add  23  to both sides of the equation :  

                     14f = 23

Divide both sides of the equation by 14:

                    f = 23/14 = 1.643

the answer is 31.27mph

i believe that the answer is

b. y-1=-2(x-4)

hope this !
