Question

Can anyone help?!

suppose f(x)=4x-2 and g(x)=-2x+1 find the value of f(5)/g(-3)

Answer 1

1.Plug in x=5 to f(x) to get number #1
2. Plug in x=-3 into g(x) to get number #2
Then divide number #1/number #2

Answer 2

Is it 2?

Answer 3

How did you get that?

Answer 4

I plugged in 5 and -3 into the equation then divided both, why is it wrong?

Answer 5

Plug 5 in f(x)=4x-2 what did you get?

Answer 6

18

Answer 7

Wait I think I messed up, is the answer 2 4/7?

Answer 8

hmm

Answer 9

\(\large \begin{array}{llll}
f(x)=4x-2
\\ \quad \\
g(x)=-2x+1
\end{array}\qquad
\begin{array}{llll}
\cfrac{f({\color{brown}{ 5}})=4({\color{brown}{ 5}})-2}{g({\color{brown}{ -3}})=-2({\color{brown}{ -3}})+1}
\end{array}\implies \cfrac{?}{?}\)

Answer 10

4*5-2 = 20-2 = 18

-2*-3+1 = +6+1 = 7

Answer 11

18/7= 2.57?

Answer 12

yeap

Answer 13

Yes 2(4/7) works

Answer 14

Ok, thank you both!
