Answer:
<h3>
<u>
x = -7</u></h3>
Step-by-step explanation:
x-coordinate of both points is the same. That means the line is parallel to Y-axis
Equation of every line parallel to Y-axis is: x = x₀
where x₀ is the x-coordinate of any point from the line
x₀ = -7 so the equation is:
<u>x = -7</u>

Remark
If you are given choices, you should quote them; Otherwise we are guessing. I will give you some some choices.
- The two angles are next to each other.
- They cannot be opposite one another.
- Opposite angles are supplementary.
- These two angles are do not add to 180
Answer:
S,Z,F
Step-by-step explanation:
i just did it
Let's say the distance is "x".
time = distance / rate
time1 = x / 40
time2 = x/80
A) time1 shoud be twice time2 or (time1 / time2) =2
B) time1 -1 = time2
Substituting equation B) into A)
((time1 / (time1 -1) = 2
time1 = 2* time1 -2
time1 = 2 hours time2 = 1 hour
Distance = 80 miles
1st trip time1 = 80/40 = 2 hours
return trip time2 = 80/80 = 1 hour
total trip = 160 miles in 3 hours
average speed = 53.333333 miles per hour
Each side would be = square root of 64 which is 8m
Perimeter = 8 * 4 = 32 m.
