Answer:
22.5
Step-by-step explanation:
If you divide y/x each ticket costs $2.5, so multiply 2.5x9 and that's your answer. :)
The answer is 10 because its in the tens place
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2
