All you would have to do is substitute!
Answer:
First one will be 2
Second one will be 10
Third one will be undefined
Explanation:
So for the first one you are substituting x for -3 so then the equation would look like this: -3^2+9/-3^2, this will equal to 9+9/9 which your answer would be 2 since 18/9 is 2. For the second one it will look like this -1^2+9/-1^2 which would be 1+9/1, this would equal to 10. For the last one it will look like this 0^2+9/0^2 which would just be 0+9/0 9/0 would be undefined.

Answer:
y=10
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
(5x2 - 2x + 1) = (x - 1)
Simplify by multiplying 5 and 2.
(10 - 2x + 1) = (x - 1)
Combine like terms. Remove parentheses.
11 - 2x = x - 1
Cancel out - 2x to get the variable on one side.
- 2x + 2x = 0 x + 2x = 3x
11 = 3x - 1
Do the same with the 1.
12 = 3x
Divide.
x = 4
