Answer:
2 1/2 hours
Step-by-step explanation:
1. multiply 12 by 2 to get 24
2. divide 12 by 2 to get 6 mph (miles per hour)
3. Add the 6 and 24
Answer:
- domain: all reals
- range: y ≥ 2
Step-by-step explanation:
The domain of any polynomial function, quadratics included, is "all reals."
The graph opens upward, so the y-value of the vertex is the minimum value of the range: y ≥ 2.

======================================
Explanation:
In this context, a zero is another term for x intercept or root. This is where the graph either touches or crosses the x axis. This occurs in three locations: x = -3, x = 2, and x = 0. So those are the three roots. That makes the first three statements true, while the remaining two others are false.
Side note: x = 0 doesn't always have to be involved. Its quite possible to have x = 0 not be an x intercept. The term "zero" is a bit misleading in that regard. I prefer either "root" or "x intercept" instead.
You can substitute it for 5.
2/5 = 0.4 = 40%
5/10 = 0.5 =50%
