Which of the following ordered pairs is a solution of the equation y=-4x^2
I REEEEEEEALLY need help I don't get it.
pick any ordered pair. Use the values in the equation. Does it work?
For example
(3,1): -4*3^2 = 1? NO
(-1,-4): -4(-1)^2 = -4? YES
anyone have the answers to the quick check?
To determine which of the given ordered pairs is a solution of the equation y = -4x^2, we need to substitute the x and y values from each ordered pair into the equation and see if the equation holds true.
Let's go through each ordered pair step by step:
1. (-2, -16):
Substituting x = -2 and y = -16 into the equation, we get:
-16 = -4(-2)^2
Simplifying the right side, we have:
-16 = -4 * 4
-16 = -16
Since -16 is equal to -16, this ordered pair (-2, -16) is a solution to the equation.
2. (0, 0):
Substituting x = 0 and y = 0 into the equation, we get:
0 = -4(0)^2
Simplifying the right side, we have:
0 = -4 * 0
0 = 0
Since 0 is equal to 0, this ordered pair (0, 0) is a solution to the equation.
3. (3, -36):
Substituting x = 3 and y = -36 into the equation, we get:
-36 = -4(3)^2
Simplifying the right side, we have:
-36 = -4 * 9
-36 = -36
Since -36 is equal to -36, this ordered pair (3, -36) is a solution to the equation.
Therefore, the ordered pairs (-2, -16), (0, 0), and (3, -36) are solutions to the equation y = -4x^2.
