Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool. In quadratic form, the area of the pool is

$2x^2-x-28$

Subtracting the area of the pool from the area of the yard:

$3x^2-14x-5-(2x^2-x-28)$

Since the negative in front of the parenthesis will change the signs inside:

$3x^2-14x-5-2x^2+x+28$

Combine like terms to get the area left after the pool goes in:

$x^2-13x+23$

Which of the following represents a function with the greatest rate of change?

defon

So the rate of change can be found in different places.

For the first one:

This equation is in slope-intercept form, or y = mx + b.

m would be the slope/rate of change, and b the y intercept. (x and y would just be any sets of ordered pairs that fit into the equation.)

So if you look at which number is in the m spot, or the rate of change spot, you see that 5 is the rate of change.

For the second one: The formula for slope is:

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

So just put in any ordered pairs in. I'm just going to put in the ordered pairs, (6, 30) and (4, 22).

Or,

m = (30 - 22) / (6 - 4)

Or,

m = 8/2

Or 4.

For the third one:

You can use the same formula as I stated above.

So you have to look for two ordered pairs here, two points.

So you can estimate that two of the points are: (0, 3) and (-2, -9).

So then just solve for that.

(-9 - 3) / (-2 - 0) = -12 / -2 = 6

For the last one:

Again, use the same equation.

m = (7 - 1) / (-1 - (-3))

m = 6/2

m = 3

So the one with the greatest rate of change would be C.

How do I do this ? I have 120 degrees but I need to solve for x

Darina [25.2K]

Since the legs are the same length, we know that the remaining two angles must be the same.

120+2x=180
2x=60
x=30

Final answer: x=30 degrees

A movie rental website charges $5.00 per month for membership and $1.25 per movie.How many movies did Andrew rent this month if

Oksanka [162]

So to start subtract $5 from $16.25 for the monthly membership
That gives you $11.25
So then you Just divide...
$11.25 divided by $1.25
which gives you 9
So bill rented 9 movies for the month

Hope this helped! :)

Eddie is practicing wind sprints during his summer break. He’s able to run 72 meters in 12 seconds. If d represents distance and

AnnZ [28]

D is distance which is 72 meters
time represents seconds which is 12
so ratio is 12:72
reduce to get 1:6
time over distance would be 1/6
every second Eddie runs 6 meters
so t= d/6
or 6t=d
