Since you earn nine dollars per hour, nine is two more an a number x.
So, we have the equation 9=2+x.
Solving for x, we get that x is equal to 7. Therefore, you earned 7 dollars per hour last year.
no correlation because as the number of people who biys tickets it doesn affect the value of the grand prize since it is chosen before the amount of tickets are sold
The vertex is on the axis of symmetry, so the axis of symmetry is x = 3. Find any two x-intercepts that have the equivalent distance from the axis of symmetry. Use those x-intercepts to write factors of the function by subtracting their values from x. For example, 2 and 4 are each 1 unit from x = 3, so f(x) = (x – 2)(x – 4) is a possible function.
