Nope, inverse of first function is
f^-1(x)= (x-1)/6
x - 3y = 1 ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
-14y = -8
-14 -14
y = ⁴/₇
x - 3y = 1
⁴/₇ - 3y = 1
- ⁴/₇ - ⁴/₇
-3y = ³/₇
-3 -3
y = ⁻¹/₇
(x, y) = (⁴/₇, ⁻¹/₇)
The answers for this question is B,F,and G. If this isn't for the Math Nation then i don't know what the answer is considering that there isn't any information to find out the answer for this question.
I think that it’s 16 probably
