Answer:
Step-by-step explanation: . y - 7 = -3⁄4 (x +5)
1. y = -3/4(x+5) + 7
2. y = -3/4x + -15/4 + 7
3. y = -3/4x + 13/4

Answer:</h3>

<h3>
Step-by-step explanation:</h3>
In this question, we're simply combining "like-terms" in order to simplify the expression.
Lets solve:

When you're done solving, you should get -17x-21
This means that -17x-21 would be the simplified version.

"h and k cannot both equal zero" -- yes, it can. if the vertex of a parabola is at (0, 0), there's nothing incorrect/invalid about that!!
"k and c have the same value" -- k and c do not have the same value. "k" is the y-value of the vertex and c is the constant in your quadratic equation, and the constant is not necessarily the y-value.
"the value of a remains the same" -- this is true. the a's in your equations are the same values, because the a-value is the coefficient of the x-variable in both equations. y = a(x - h)^2 and y = ax^2 -- both of these have a applying to your x-variables.
"h is equal to one half -b" -- this isn't true. the formula for calculating the x value of the vertex (h is the x-value of the vertex) is h = (-b/2a). -b/2a is not the same as one half -b because this answer choice doesn't involve the a-value.
x and the 120 degrees are Complementary angles so they are the same. x=120˚
