G(x)= -x^2-3
So the answer is A
Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1
Answer:

Step-by-step explanation:
Solving for x:

In this form is easy to identify the factors of the quadratic function:
. The two solutions are the values that make each of the factors equals to zero.

Answer:
D
Step-by-step explanation:
I can say that Jared and Nicole are correct because they manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. They can also write the equation as x as a function of y and substitute it to x in the other equation and solve for y. For both solution, they will still obtain the same answers.
