Answer:
-1
Step-by-step explanation:
9(x+2)=5−2(x−1)
9x+18=5−2(x−1)
9x+18=5−2x+2
9x+18=7−2x
9x+18+2x=7
11x+18=7
11x=7−18
11x=−11
x= 11
/−11
x=-1

Inverse of the function 2x-6y=1
To get the inverse of the function, first, interchanged
the variables such x will be y and y will be x.
<span>(1) </span><span> 2y – 6x = 1</span>
Then, find the value of y in the new equation,
<span>(2) </span><span> 2y – 6x + 6x = 1 + 6x</span>
2y
= 1 + 6x
<span>(3) </span>(1/2)(2y)
= (1 + 6x)(1/2)
<span> y = (1 + 6x) / 2</span>
<span>The reverse of the function
is y
= (1 + 6x)/2.</span>
