<h2>The Domain and Range of a Set of Ordered Pairs</h2><h3>Answer:</h3>

Domain: x \in \{ 1, 3, 5, 8 \}

Range: y \in \{ 2, 4, 6, 9 \}

<h3>Step-by-step explanation:</h3>

We are given the set of ordered pairs: R. The Domain is just the set containing all the x values of each ordered pair of R. Recall that in the ordered pair (a,b), a is the x value. In set R, we can see that the x values are \{ 1, 3, 5, 8 \}.

For the Range, it is just the set containing all the y values of each ordered pair of R. Recall that in the ordered pair (a,b), b is the y value. In set R, we can see that the y values are \{ 2, 4, 6, 9 \}.

Y/3 - 4 = -1 solve for y
Marysya12 [62]

Answer:

y=9

Step-by-step explanation:

First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction

y/3 -4= -1

y/3= 3

Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.

y/3=3

y=9

Thus we get that the value for y is 9.

Hope this helped!

Btw you're very pretty! <3

X + 9 = 18 + -2x what does x epual
babymother [125]

Answer:

x = 3

Step-by-step explanation:

Step 1: Write out equation

x + 9 = 18 - 2x

Step 2: Add 2x on both sides

x + 2x + 9 = 18 - 2x + 2x

3x + 9 = 18

Step 3: Subtract 9 on both sides

3x + 9 - 9 = 18 - 9

3x = 9

Step 4: Divide both sides by 3

3x/3 = 9/3

x = 3
