WILL GIVE A BRAINLIEST IF UR CORRECT PLEASE HELP!!

7 0

A pair of numbers is a solution of y = -3x if the second number, y, is -3 times the first number, x.

What about the pair (-1, 4)? If you replace x with -1, you get y = -3(-1) = 3, not 4. So (-1, 4) is NOT a solution.

For each answer choice, you have to check all three of the given pairs.

(0, 0) is a solution because if x = 0, then y = -3(0) = 0.
(3, -9) is a solution because if x = 3, then y = 3(-3) = -9.

Can you finish it?

<h2>Solving for the x-intercepts of a Parabola given the Equation</h2><h3>Answer:</h3>

$x = 3$ and $x = 1$

<h3>Step-by-step explanation:</h3>

$x$ -intercepts are just the values $x$ when $y = 0$ .

Solving for $x$ :

$0 = -4(x -2)^2 +4 \\ -4(x -2)^2 +4 = 0 \\ -4(x -2)^2 = -4 \\ 4(x -2)^2 = 4 \\ (x-2)^2 = \frac{4}{4} \\ (x -2)^2 = 1 \\ x-2 = \pm \sqrt1 \\ x -2 = \pm 1 \\ x = \pm 1 +2$
