Answer: y=-61/2
Step-by-step explanation: - 4(8 + y)/-4 = 90/-4
8+y-8=-45/2-8
-8(2)-45/2
-16-45
-61
y=-61/2
The distance from city C to city D is 4,814 miles.
At a speed of 40 mph, it would take 15 minutes to drive to the mall
The first step to take in order to determine the answer is to determine the distance driven to the mall. This information is not given so it has to determined.
Distance = speed x total time
- speed = 30 mph.
- time = 20 minutes
Speed is measured in hours, while time is measured in minutes. Both data has to be converted to the same time measurement
To convert time to hour, divide by 60 = 20 / 60 = 1/3
Distance = 1/3 x 30 = 10 m
The second step is to use the distance determined in the previous step to determine the time it would take to travel at a speed of 40 mph
Time = Distance / Average Speed
10 / 40 = 1/4 hours
To convert hours to minutes, multiply by 60 :1/4 x 60 = 15 minutes
In order to determine the time that it would take to drive to the mall, first determine the distance to the mall. Use the distance and speed to determine the time

The x coordinate remains the same.
The Y coordinate changes from a positive number to a negative number.
This means that the figure is reflected across the X axis because positive Y values are above the X axis and negative Y values are below the X axis.
The answer is D.
Should be 18x^4-12x.
Let me know if you want more of an explanation.
