Could someone help me with 31 and 32 I will crown and thank

B;A

Step-by-step explanation:

31. Because you are adding 4 to the y value, you are subtracting 4 verically, moving it down 4 units.

32. The vertex formula is y = a(x-h)+k ,where (h,k) is the vertex, and you find the value of "a" based off of another point on the graph.

you should at least use a calculater

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
