Answer:

The relation is a function!

Your Domain should be...

{-1, 1, 7, 9}

Your Range should be...

{-1, 8, 9}

WHY?

Your domain is always your x-coordinates, which are the first coordinates in a pair.

Your range is always your y-coordinates, which are the second coordinates in a pair.

When listing the points, it's important to remain a relation CANNOT be a function if the x's repeat, so luckily, they do not repeat.

Also, when listing points for your range, remember, if they repeat, you should only count one of the numbers, as you can see from the answer, there was two nines, but instead I put one.

MrMuchimi

Answer:

Video Games = $5.25

Movies = $1.25

Step-by-step explanation:

(3x + 5y = 30)2

6x + 2y = 18

                                           Video Games (y) = 5.25

  6x + 10y = 60

<u>-  6x + 2y = 18   </u>

      (8y)/8 = (42)/8

<u>                                                                                </u>

6x + 2(5.25) = 18

6x + 10.5 = 18

6x = 7.5

x = 1.25

Double Check by plugging in the numbers

M+(-9.5)=-7.8 how do you do this problem
krok68 [10]
M + (-9.5) = -7.8

First, simplify your brackets. / Your problem should look like: m + -9.5 = -7.8
Second, change addition to subtraction. / Your problem should look like: m - 9.5 = -7.8
Third, add 9.5 to both sides. / Your problem should look like: m = -7.8 + 9.5
Fourth, simplify. / Your problem should look like: m = 1.7

Answer: m = 1.7
