and
so
and you rationalize denominator by multiplying numerator and denominatr by so that gives--
Your answer is
Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $35 and same-day tickets cost
2 answers:
For this case we have:
x: Variable representing the types of advance input
y: Variable representing the same-day entry types
We have according to the cost:
According to the number of tickets:
We have a system of two equations with two unknowns:
We multiply the second equation by -35:
We add:
Thus, 40 same-day tickets were sold.
20 advance tickets were sold
Answer:
20 advance
40 same-day

Answer:
Choice A) x and f(x) approach negative infinity
Choice D) x and f(x) approach positive infinity
Step-by-step explanation:
A cubic curve starts low and ends high if the leading coefficient is positive, which in this case it is. This means that the left side of the graph falls while the right side rises. Your teacher might say something like "fall to the left, rise to the right" to describe what the end behavior is doing.
More formally "fall to the left" means that as x approaches negative infinity, y = f(x) is approaching negative infinity as well. Similarly, "rise to the right" indicates that as x approaches infinity, y = f(x) heads off to infinity as well. Both x and y = f(x) move in the same direction along their respective number lines; eg, if one goes in the negative direction, then so does the other.
The graph below confirms the answer visually.
