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

A pair of opposite rays would be?

natita [175]

Answer:

Option C) PA and PB

Step-by-step explanation:

PA and ray PB are opposite because they are moving towards opposite direction and making an angle of 180 degrees.

On the other hand rays AP and BP are pointing toward each other.

AP and PZ are perpendicular to each other because they are making an angle of 90 degrees.

Whereas PW and PZ are making an angle of 45 degrees.

Solve the quadratic equation for x. What is the largest solution to the equation? 5x2 + 30x + 25 = 0 A) x = 5 B) x = 1 C) x = ?1

Darina [25.2K]

Answer:

x= -1 (looks like C)

Step-by-step explanation:

To solve for x, factor the quadratic. Begin by factoring out a GCF of 5.

$5x^2+30x+25 = 5(x^2+6x+5)$

To factor the remaining parts of the quadratic, look for two factors of 5 which add to 6. This would be 1 and 5.

So the quadratic factored is:

$5(x^2+6x+5) = 5(x+1)(x+5)$

To solve for x, set each factor equal to 0 and solve.

x+1 = 0

x = -1

x+5 = 0

x=-5

-1 is the largest solution.
