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

if the angle HMA is a right angle, the measure of angle SMH = 66 degrees, and angle SMH is complementary to angle HME, find the

makvit [3.9K]

Answer:

SMA= 24 degrees

Step-by-step explanation:

add the other given angles together: 66 + 90= 156

subtract 158 from 180 (every triangle has a total of 180 degrees): 180-156 = 24

3x+3y=10<br> -9x-9y=-30<br> please help

tiny-mole [99]

Answer:

Infinitely many solutions.

Explanation:

In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).

Equation no 1:

3x + 3y = 10

Equation no 2:

-9x - 9y = -30

Now multiply equation no 1 with (3 )

3(3x + 3y) = 3(10)

9x + 9y = 30 ( equation no 1 )

Now ADD both the equations

9x + 9y = 30

<u> -9x - 9y =-30</u>

0 = 0
