Answer:
element -4 and subset 0
Step-by-step explanation:

Recall your d = rt, distance = rate * time.
let's say the rate of speed for Kala was "r" on the way over to the mountains.
Now, on the way over, it took 8 hours due to heavy traffic, whilst on the way back it took only 5 hours since there was no traffic.
The distance covered, say "d" miles, is the same on the way over as well as on the way back.
Answer:
I think the answere is 100 because i took a guess
Step-by-step explanation:
Given:
<span>A: 3x + y = 6
</span><span>B: 6x - 2y = 4
</span><span>C: y = 3x - 2
</span><span>D: y = 1/3 x + 7
To figure out which two lines are perpendicular, we must look at the slopes of each one after putting them into standard form, y = mx + b.
Standard Form:
A: y = -3x + 6
B: y = 3x - 2
C: y = 3x - 2
D: y = (1/3)x + 7
Lines are perpendicular when their slopes are opposite inverses of eachother.
The opposite of -3 is 3 and the inverse of 3 is 1/3.
Therefore, lines A and D are perpendicular to one another :)
