It is y=x-150 because x−150+150=y+150
<span>The curve formed by a quadratic equation is called a PARABOLA</span>
Answer:

Step-by-step explanation:
We have the following variables:
y: hours of sleep
x: age
Each day, a young person should sleep 9 hours
This means that y is 9 added to something
plus 1 4 hour for each year that the person is under 18 years of age.
For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.
So the equation relating hours of sleep y and age x is:

Step-by-step explanation:
Given
f(x) = 2x
f(3) = 2 * 3 = 6
Hope it will help):)
-9=x+10
-19=x
The answer is -19
