Answer:

#7.

The domain is {-3,0,4}

the range is {-5,0,1,7}

not a function

#8

D={3,6,12,18}

R={5,7,9,10}

not a function

Step-by-step explanation:

First, 7.

the domain is the all of the x values, in numerical order, listed once, even if it repeats.

D={-3,0,4} (notice how -3 is listed twice; despite that, we only list it once)  

the range is all of the y values, in numerical order, listed once, even if the numbers repeat

R={-5,0,1,7}

A function can have the range (y values) repeat, however, the domain (x values) cannot repeat.

Therefore, this is not a function, since -3 is listed twice.

For 8.

The domain, can be listed as

D={3,6,12,18}

And the range as

R={5,7,9,10}

Notice how it says that if 6 is the input (x), the output (y) can be 5 or 10. Since we said the domain CANNOT repeat, this isn't a function.

Hope this helps!

Lelu [443]

Reorder from least to greatest.

4, 4, 6, 6, 6, 8, 10, 15, 15

                /\

Median is the middle number.

This would be 6.

Find the value of x.
love history [14]

Answer:

x is 64 degrees

Step-by-step explanation:

Since the polygon is a quad we know all the angles add up to 360. So, we can do :

100 + 130 + 66 = 360 - x

296 = 360 - x

Subtract 360 on both sides

-64 =  -x

Multiply by negative one on both sides and we get

64 = x

x is 64 degrees
