Answer:
(x) = x + 8
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9(x - 8) ← divide both sides by 9
= x - 8 ( add 8 to both sides )
+ 8 = x
Change y back into terms of x with x = (x) , thus
(x) = x + 8
Answer:
could you show a picture
Step-by-step explanation:
please then i could answer
I can help with the piecewise function
I don't think I can correctly format it very well on my computer so I can give you the points if you can fill it in correctly.
f(x)=4 if x≤-2
f(x)= -x if -2<x<2
f(x)= -3 if x≥2
Hopefully this helps. I don't think I can help with problem #1. Sorry
$275*x%=195
It will be a 29% reduction. But it will not have the exact cost of $195
Answer:
Step-by-step explanation:
5y - 2y = 10
3y = 10
y = 10/3 = 3⅓
