Answer:
x = 5
y = 0
Step-by-step explanation:
3x + y = 15
3x -y = 15
Add the two equations;
6x = 30
Inverse operations;
6x = 30
/6 /6
x = 5
Back substitute;
3(5) + y = 15
15 + y = 15
y = 0
The easiest way to evaluate the limit is to simply subsitute the value into the function
as x approaches -3
just subsitute -3 for x
(-3)³=(-3)(-3)(-3)=-27
answer is -27
