Question

= f(x)=-2X+13 for f(10)

Answer 1

F=1+1/2

Explanation:

(10)=-2F+13

We move all terms to the left:

(10)-(-2F+13)=0

We get rid of parentheses

2F-13+10=0

We add all the numbers together, and all the variables

2F-3=0

We move all terms containing F to the left, all other terms to the right

2F=3

F=3/2

Answer 2

-6

Explanation:

f(x)=-2x+13

f(10)=-2(10)+14

f(10)=-20+14

f(10)=-6
