Complete the following steps for this equation.

Troyanec [42]

1. <span>4x – 20 = 5y

so 5y = </span><span>4x – 20

divide both sides by 5

y = (4/5)x - 4

2. x-intercept is at y=0

so (4/5)x - 4 = 0

x = 5

so it is (5,0)

3. y-intercept is at x=0, y = 0 - 4 = -4

so it is (0,-4)

Question 1 of 10

Archy [21]

Answer:

A. y = 7(x + 1)²-3

Step-by-step explanation:

Parabola:

$y = 7x^{2} + 14x + 4$

$y = 7(x^{2} + 2x) + 4$

Putting into vertex form, remember that:

$(x + a)^{2} = x^{2} + 2ax + a^{2}$

In this question:

$x^{2} + 2x$ , to put into this format:

$x^{2} + 2x + 1 = (x + 1)^{2}$

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then

Vertex form:

$y = 7(x^{2} + 2x + 1) + 4 - 7$

$y = 7(x + 1)^{2} - 3$

So the correct answer is:

A. y = 7(x + 1)²-3
