Answer:
{(1, 2), (3, 4)}
Step-by-step explanation:
If you want both the relation and its inverse to be functions, there can be no repeated x-values, and no repeated y-values.
In the above pair of points, I have avoided duplicates by making all of the values different. That is not necessary, but it satisfies this problem easily.
An hour is 60 minutes.
The trip to the arena + The return drive = 60 mintues.
Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.
The return drive + 8 minutes = The trip to the arena
Let's represent these two equations with variables.
x + r = 60
r + 8 = x
What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.
x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26
Then use r in an earlier equation to find a.
r + 8 = x
26 + 8 = x
x = 34

Answer:
20 inches
Step-by-step explanation:
Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by
A =1/2(a + b)h where a = length along the top of the cape = 24 in, b = length along the bottom of the cape = 36 in and h = height of the cape
So, h = 2A/(a + b)
= 2 × 600 in²/(24 in + 36 in)
= 1200 in²/60 in
= 20 in
So, the height of the cape is 20 inches
