Vertex coordinates: (h, k)
Vertex form: y = a(x-h)^2 + k
y = 2(x+3) + 2(x+4)
Use distributive property:
y = 2((x+3)+(x+4))
Simplify:
y = 2(2x+7)
y = 4x+14
This is slope - intercept form, not vertex form. Vertex form is for quadratic equations - this is a linear equation.
Answer (in slope - intercept form):
y = 4x+14
Answer:

Step-by-step explanation:
Answer:
-54
Step-by-step explanation:
The name Quadratic<span> comes from "quad" meaning square, because the variable gets squared (like x</span>2<span>). However, it is important to not that an expression is only quadratic if and only if the highest degree of a term is 2. Therefore, the quadratic equations from the pool of choices would be as follows:
</span><span>3x^2 + 5x - 7 = 0
</span><span>5x^2+ 15x = 0
</span><span>x^2 - 4x = 4x + 7</span>
