Answer:
x=7
Step-by-step explanation:
The domain is the same as the x value and the range is the same as the y value, so you just plug in the 3 to all the x's.
the range of the function is 17
The answer is j+5-2
because sum means to add
Answer:
21/5 =x
Step-by-step explanation:
5x + 7 - x - 2 = 6x + 3x – 16
Combine like terms
4x +5 = 9x - 16
Subtract 4x from each side
4x+5 -4x = 9x-4x-16
5 = 5x-16
Add 16 to each side
5+16 = 5x-16+16
21=5x
Divide each side by 5
21/5 = 5x/5
21/5 =x
Yes, because there are common factors in the equation. therefore showing you can group
