The top right is a function, because no point cross twice over the y axis
Hello there!
To do this, we will take the square root from each side
4^2 would be 4
16 would be 4
4 = 4
I hope I helped!

One potato...at least i think so
2 figures are congruent if at least 2 sides are the same length, there angles are the same, etc
Multiply first equation with 2. Then add first and second, we get -x=6. X=-6 and y=-29
