Answer:

m(x)

Step-by-step explanation:

they would have to pass the horizontal line test and the vertical line test for both the origional and the inverse.

b(x) does not pass the horizontal line test in any of the y values over 3

d(x) does not pass the horizontal line test for y=-9

p(x) does not pass the horizontal line test for positive y values

and m(x) has only one corresponding x value for every y value

lara [203]

Answer: School Y has 4 points and School X has 12 points.

Explanation:

Let the number of points School Y has be x

Let the number of points School X has be 3x

According to question, we get

$3x-x=8\\\\2x=8\\\\x=\frac{8}{2}\\\\x=4$

So, the number of point School Y has 4.

and number of points School X has

$3x=3\times 4=12$

Hence, School Y has 4 points and School X has 12 points.

Find the distance between the points (–3, 2) and (0, 3).

Oksi-84 [34.3K]

Answer: $\sqrt{10}\ units$

Step-by-step explanation:

You need to use the following formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given the points (-3, 2) and (0, 3), you can identify that:

$x_2=-3\\x_1=0\\\\y_2=2\\y_1=3$

Then, the final step is to substitutes these coordinates into the formula.

So, the distance between the given points is:

$d=\sqrt{(-3-0)^2+(2-3)^2}\\\\d=\sqrt{10}\ units$
