Answer:
f(2) =8
Step-by-step explanation:
f(2) Is when n=2
f(2) = -5 *f(2-1) -7
f(2) = -5 *f(1) -7
We know that f(1) = -3
f(2) = -5 *-3 -7
= 15 -7
= 8
6(2 - 7v) - 4(-6v + 7)
multiply the first bracket by 6
(6)(2)=-12
(6)(-7v)=-42v
multiply the second bracket by -4
(-4)(-6v)=-24v
(-4)(7)=-28
12-42v+24v-28
-16-18v
Answer:
-16-18v or -18v-16
