If the slopes of the 2 lines are equal then they are parallel.
If m1m2 = -1 (where m1 and m2 are the slopes of the 2 lines) then they are perpendicular.
If the 2 slopes do not match either the first or second conditions then they are neither parallel or perpendicular.
Part A:
Six Tents Holds 42 People
Nine Tents Holds 63 People
10 Tents Holds 70 People
Part B:
Number of tents|||Number of people
1 |||7
6 |||42
9 |||63
10 |||70
Part C:
Tents=x
1x=7 people
7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
Answer:
$9918.30
Step-by-step explanation:
The total tax is ...

Answer:
125
Step-by-step explanation:
First, solve the exponent:
5^2 = 5x5 = 25
Then solve the rest:
5x25-125
