1. Which of the following ordered pairs is a solution of the equation y=4x^2? (1 point)
A. (-2, 16) ***My answer***
B. (1, -8)
C. (0, -4)
D. (2, -16)
-2 = 16^2 Nope!
So then whats the answer?
Y = 4x^2 = 4*(-2)^2 = 4 * 4 = 16.
(-2, 16).
My answer is A.
A C C B D A C B
To determine which of the given ordered pairs is a solution to the equation y = 4x^2, we need to substitute the x and y values into the equation and see if both sides are equal.
Let's go through each option:
A. (-2, 16):
Substituting x = -2 and y = 16 into the equation, we have:
16 = 4(-2)^2
16 = 4(4)
16 = 16
Since both sides are equal, this ordered pair (-2, 16) is a solution to the equation.
B. (1, -8):
Substituting x = 1 and y = -8 into the equation, we have:
-8 = 4(1)^2
-8 = 4(1)
-8 = 4
Since both sides are not equal, this ordered pair (1, -8) is not a solution to the equation.
C. (0, -4):
Substituting x = 0 and y = -4 into the equation, we have:
-4 = 4(0)^2
-4 = 4(0)
-4 = 0
Since both sides are not equal, this ordered pair (0, -4) is not a solution to the equation.
D. (2, -16):
Substituting x = 2 and y = -16 into the equation, we have:
-16 = 4(2)^2
-16 = 4(4)
-16 = 16
Since both sides are not equal, this ordered pair (2, -16) is not a solution to the equation.
Therefore, the only ordered pair that is a solution to the equation y = 4x^2 is A. (-2, 16).
