Passes through (-3, 1) and perpendicular to x=0
igomit [66]

Answer:

Find the equation of the line perpendicular to x = 0 that passes through (-3,1)

Step-by-step explanation:

Using the equation, y - y1 = m(x - x1)

Since x = 0, the gradient, m = 0

Hence, y - 1 = 0

∴ y = 1

Is each expression equivalent to 2x^2 - 50?
puteri [66]
We would first determine how to solve this, and then from there, we would then see whether the following answer would be the correct answers.

2x^2 -  50 \\ \\ Pull \ out \ like \ factors : \\ &#10;&#10;   2x^2 - 50  =   2 * (x^2 - 25) \\ \\    Factoring: \\    x^2 - 25 \\ \\ (your \  answer)...\\ \\   2 * (x + 5) * (x - 5)

Now, we can determine whether the say "yes" or "no" to the following answers.

<span>a 2(x-5)(x+5) = YES
b -2(x+5)(x+5) = NO
c -2(5-x)(x+5) = NO</span>
