Answer:
x = 5
Step-by-step explanation:
This equation can be rearranged in order to easily solve.
First, rearrange the equation by simply flipping it.
3x + 30 = 9x → 9x = 3x + 30
Then, you may solve for x.
9x = 3x + 30 subtract 3x from both sides of the equation
6x = 30 divide by 6 on both sides of the equation
x = 5
Because if you a model your not going to get the right answer
Answer:
if you see the graph for x=-1
the y is equal -4
you can draw a straight line parallel y axes from point x=-1 it will cut the graph on y=-4
Check the picture below. So,the parabola looks like so, notice the distance "p". since the parabola is opening to the right, then "p" is positive, thus is 5.

The domain is always all real numbers.
