Question

W(x )= -2x + 7 when x = -3 I already know the answer but I need the work shown because that is what I don't understand.

Answer 1

Hey there!!

w(x) = -2x + 7

x = -3

Now, we plug in the value of -3 instead of x

...w(-3) = -2(-3) + 7

...w(-3) = 6+7

...w(-3) = 13

Hence, the required answer is 13

Hope my answer helps!!

Answer 2

W(x) = -2x + 7

W(3) = -2(-3) + 7 this is when x = -3

= 6 + 7

= 13

***********************************************

If you meant to type in: W(x) = -3 then

-3 = -2x + 7

-10 = -2x

`(-10)/(-2) = (-2x)/(-2)`

5 = x
