Answer:

<h2>9p</h2>

Step-by-step explanation:

9p - 8 + 8

9p - 0

9p

-8 + 8 cancel out.

9p is a variable, and its own term with no like terms. so you leave it alone.

That gives you 9p

Which equation represents a graph with a vertex at (–3, 2)?

lesya [120]

<u>We will proceed to find the equations in the vertex form in each case</u>

<u>Part a)</u> $y= 4x^{2}+24x+38$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-38= 4x^{2}+24x$

Factor the leading coefficient

$y-38= 4(x^{2}+6x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$y-38+36= 4(x^{2}+6x+9)$

$y-2= 4(x+3)^{2}$

$y= 4(x+3)^{2}+2$

<u>the vertex is the point $(-3,2)$ </u>

<u>Part b)</u> $y=4x^{2}-24x+38$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-38= 4x^{2}-24x$

Factor the leading coefficient

$y-38= 4(x^{2}-6x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$y-38+36= 4(x^{2}-6x+9)$

$y-2= 4(x-3)^{2}$

$y= 4(x-3)^{2}+2$

<u>the vertex is the point $(3,2)$ </u>

<u>Part c) </u> $y=4x^{2}+12x+2$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-2= 4x^{2}+12x$

Factor the leading coefficient

$y-2= 4(x^{2}+3x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$y-2+9= 4(x^{2}+3x+2.25)$

$y+7= 4(x+1.5)^{2}$

$y= 4(x+1.5)^{2}-7$

<u>the vertex is the point $(-1.5,7)$ </u>

<u>Part d)</u> $y=4x^{2}+16x+13$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-13= 4x^{2}+16x$

Factor the leading coefficient

$y-13= 4(x^{2}+4x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$y-13+16= 4(x^{2}+4x+4)$

$y+3= 4(x+2)^{2}$

$y= 4(x+2)^{2}-3$

<u>the vertex is the point $(-2,-3)$ </u>

therefore

<u>the answer is </u>

$y= 4x^{2}+24x+38$

Mateo made the model below to represent the number of miles he swims in the

Rama09 [41]

Answer:

Step-by-step explanation:the number of times Mateo swims each week is represented by the...4 rectangles...in the model.

The distance, in miles, that Mateo swims each time he goes to the pool is represented by the...2 shaded sections out of 3 in 1 rectangle.

The total distance Mateo swims each week can be determined using the expression...8/12 x 2/3 which is equivalent to...4/9 miles.
