15) 8

16) -2

Step-by-step explanation:

For each problem, use 4 where there is an x and -3 where there is a y!

15) 11+y=? If y=-3 it is 11+(-3) and that is 8!

16) x+(-6)=? If x=4 it is 4+(-6) and that is -2!

The other ones seem to be missing something so I don't understand those, but if you need more help reply to this and I'll help!

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
