Remember you can do anything to an equation as long as you do it to both sides

and when multiply by negative, flip sign

8+h>2+3h
minus h both sides
8+h-h>2+3h-h
8+0>2+2h
8>2+2h
minus 2 both sides
8-2>2-2+2h
6>0+2h
6>2h
divide by 2 both sides
6/2>2h/2
3>1h
3>h

2(2x + 3) = -6(x + 9)

sergeinik [125]

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.

A rectangles width is 5 feet less than its length. Write a quadratic function that expresses the rectangles area in terms of its

Ira Lisetskai [31]

Answer:

Area = L²-5L

Step-by-step explanation:

Area = length * width

Length = L

Width = L - 5

Area = L * (L-5) = L²-5L

Line Equation from Two Points

Verdich [7]

Hi!

We can use <u>point-slope form </u>to solve this.

$y-y_{1} =m(x -x_{1})$

$y_{1}$ <em> and </em> $x_{1}$ <em> will be from one of the points.</em>

<u>First, we have to find </u> $m$ <u>, the slope. We can use the slope equation to get this.</u>

$\frac{y_{1} -y_{2} }{x_{1} -x_{2} }$

<em>Plug in your points:</em>

$\frac{4-0}{8-(-8)} =\frac{4-0}{8+8} =\frac{4}{16} =\frac{1}{4}$

Your slope is $\frac{1}{4}$

<u><em>Now plug points and slope into point-slope equation. We will use (8, 4).</em></u>

$y-4=\frac{1}{4} (x-8)$

Now, if you want to get it into y = mx + b form, you have to solve for y:

$y-4=\frac{1}{4} (x-8)$

$y-4=\frac{1}{4} x-2$

$y=\frac{1}{4} +2$

Your equation is $y=\frac{1}{4} +2$

Which expression is equivalent to?

guapka [62]

Answer: $\frac{2x\sqrt[4]{y^{2}}}{3}$

Step-by-step explanation:

$\sqrt[4]{\frac{16}[81}} \sqrt[4]{\frac{x^{11}y^{8}}{x^{7}y^{6}}}\\\\=\frac{2}{3} \sqrt[4]{x^{4}y^{2}}\\\\=\frac{2x\sqrt[4]{y^{2}}}{3}$

If a new car is valued at $26,000 and 10 years later it is valued at $7000, then what is the average rate of change

frez [133]

Answer:

The change in value is 19,000 altogether and 1900/year

Step-by-step explanation:

Change in value:

initial value - final value

= $26,000 - $7000

= $19,000

Change in value/year:

change in value/time

= $19,000/10

= $1900/year
