Answer:
2488 miles
Step-by-step explanation:
The relevant relationship is ...
distance = speed × time
For each leg ...
distance 1 = (264 mi/h) × (2 h) = 528 mi
distance 2 = (490 mi/h) × (4 h) = 1960 mi
Then the total distance traveled in the 6 hours is ...
distance traveled = distance 1 + distance 2 = 528 mi + 1960 mi
distance traveled = 2488 mi
Answer:
Domain: all real numbers
Step-by-step explanation:
This graph is a parabola. It's equation looks like it should be:
y = x^2 - 1
If you have a graph and are looking for the domain, you are determining where the graph exists. For what x's the graph exists. If you have the equation then the domain is what x's may be put into the equation. There are no limitations on what numbers can go into this equation so the domain is all real numbers.
There are several ways to write the domain is all real numbers, set builder notation and interval notation. But the main idea is that it is all real numbers.
Answer:
Step-by-step explanation:
-4s - 7 = 29 + 5s
Subtract 5s from both sides [-4s - 5s - 7 = 29 + 5s - 5s]
-9s - 7 = 29
Add 7 to both sides [-9s -7 +7 = 29 + 7]
-9s = 36
Divide both sides by (-9) [-9s/-9 = 36/-9]
s = -4
