Answer:
=15x-7-23+2
=-8x-7+2
=-8x-5
Step-by-step explanation:
The correct answer for this problem is C.) reflection across y=x .
we have

we know that

so

two solutions
<u>first solution </u>


the first solution is the interval---------> (-1,∞)
<u>second solution</u>




the second solution is the interval---------> (-∞,-1)
therefore
the solution is all real numbers except the number
