Answer: {-2, -1, 2}</h3>
The range is the set of all possible y values. So we just list the y coordinates of each point. We only list each unique one ignoring any duplicates.
Answer:129-32
Step-by-step explanation:Decreased means subtract from that number, so you are going to subtract the 2 numbers.
The last choice because all the numbers are plotted correctly
You can solve this two ways:
One is by substituting in the numbers until you get 15=15.
6(0)-9=15
0-9=15
-9=15
6(1)-9=15
6-9=15
-3=15
6(2)-9=15
12-9=15
3=15
6(3)-9=15
18-9=15
9=15
6(4)-9=15
24-9=15
15=15
Solution is x=4
or you can find the value of x
by first adding 9 to both sides to get x by itself
6x-9=15
6x=24
Then divide by 6
x=4
