Given f(x)=x+5 all over 3, solve for f^-1(3) (A. -1; B. 14; C. 18; D. 21)

Answers

Answer 1

Answer:
f^-1 means finverse
find finverse then subsitute 3 for x
to solve

replace f(x) with y
solve for x
switch x with y
replace y with finverse or f^-1

f(x)=(x+5)/3
y=(x+5)/3
3y=x+5
3y-5=x
3x-5=y
finvers=3x-5

fiinverse(3)=3(3)-5
finverse(3)=9-5
finverse(3)=4

-13=7d+64 what is the answer

Answers

Step 1: move 64 to a left side, -13 - 64 = 7d

Step 2: -77 = 7d

Step 3: $(-77)/(7)$ = d

Step 4: d = -11

it is d=11
because u subtract the negative 64 with a positive for a positive and negative turn 0 then u got to do the same side with -13-(-64)=7d then u add -13+-64=77 after u done that it will be 77=7d divide it by 7 on both side then u get d=11
