Answer:
13. i may be wrong im not sure
Rearrange so x is the subject:-
(im assuning the f unction f(x) = (x + 2) / 7):-
f(x) = (x + 2)/7
7f(x) = x + 2
x = 7f(x) - 2
replace f(x) by x and x by another function
f = 7x - 2
Its D
Answer:
<h2><em><u>x = 4</u></em></h2>
Explanation:
10 + 6x + 2x - 7 = 35
- Add Similar Elements: 6x + 2x = 8x
10 + 8x - 7 = 35
8x + 10 - 7 = 35
8x + 3 = 35
- Subtract 3 From Both Sides
8x + 3 - 3 = 35 - 3
8x = 32
8x / 8 = 32 / 8
<h2><u><em>x = 4</em></u></h2>
