Look at the graph picture I attached

c is the intercept, which is why the graph crosses the y-axis at +3
to find where it crosses the x-axis, we make y = 0

(-4)^2-4(1)(5)
16-4(1)(5)
16-4(5)
16-20
-4
The discriminant is negative so there are no real number solutions.
Answer:
150 is 100% of 150
Steps to solve "150 is 100 percent of what number?"
We have, 100% × x = 150
or,
100
100
× x = 150
Multiplying both sides by 100 and dividing both sides by 100,
we have x = 150 ×
100
100
x = 150
If you are using a calculator, simply enter 150×100÷100, which will give you the answer.
