What is the correct evaluation of 4x2 + 4x - 2y2 +3y, when x is equal to -2 and y is equal to 3?
1 answer:
Answer:
-1
Step-by-step explanation:
This all comes down to the substitution. I am assuming that (4x2) is meant to be 4x^2 so I will solve as that.
4(-2)^2 = 4(4) = 16
4(-2) = - 8
-2(3)^2 = -2(9) = -18
3(3) = 9
16-8-18+9= -1

11=11
That is the solution.
I hope this helps!

true: y = 9 would give us a straight line because of two reasons:
a: we don’t know if x is rising
b: we don’t have an x in the equation
