Question

Given the function f(x) = −2x + 8, find x if f(x) = 14

Answer 1

f(x)=-2x+8 & f(x)=14

so, -2x+8=14
solve for x :)

Answer 2

how ? im pelletty at algebra

Answer 3

sh1tty

Answer 4

Answer 10

how u get six from that ?

Answer 11

u r incorrect :(

Answer 12

ok sry i got it

Answer 13

-2x+8=14
-2x=7/4
-x=7/4*2
x=-7/2

Answer 14

since f(x)=-2x+8 & also 14

so -2x+8=14

now i subtract 8 from both sides & then divide -2 from both sides @kristopher101495 :)

Answer 15

f(-7/2)=-2(-7/2)+8=7+8=15

Answer 16

ok @kristopher101495
