1) Distribute
Y=x^2-1x+2x-2
2) Combine like terms
Y=x^2(-1x+2x)-2
3) Slove
Y=x^2+1x-2
Answer
Y=x^2 + 1x -2
Answer: B(3)
Explanation: 12+9=21 so since 4+3 only equals 7, you plug in x as 3... since 7x3 is 21 that helps make the statement true bc both equations are equal.
There is an infinite number of values that are in both the domain and range.
The answer is y=12.75x
12.75(2)= 25.5
12.75(4)= 51
12.75(5)= 63.75
12.75(8)= 102
