Answer:
When y=7,9 the answer is yes when it = -10,-8 the answer is no.
Step-by-step explanation:
Simple substitution gets us the resulting values. for y=7 we get
which is true. For y=9 we get
which is also true. For the other values we get a negative number which is not a solution.
Square root of 4 is 2
Square root of 9 is 3
7 is between 4 and 9, so its square root is somewhere between 2 and 3, which means the correct answer is between P and Q
A, because 2+6= 8 and on the coordinate plane -8 is 6 spaces away from -2 on the x axis
