The answer is B. 21

f(x) = 4(2)^2 + 5
f(x) = 4(4) + 5
f(x)  = 16 + 5

f(x) = 21

Substitute 2 for x

f(2)=4(2)^2+5
f(2)=4(4)+5
f(2)=16+5
f(2)=21

5/6 (x - 1) = 4 what Is x
vfiekz [6]
5/6(x-1)=4
(x-1)=(4*6)/5
x-1=24/5
x=24/5  +  1
least common multiple=5
x=(24+1*5)/5
x=29/5

Answer: x=29/5

To check:

5/6(x-1)=5/6(29/5  -1)=5/6[(29-5)/5]=5/6(24/5)=(5*24)/(6*5)=120/30=4
