Answer:
Step-by-step explanation:
Let's use the variable Y to represent the length of time (in seconds) that the traffic light remains yellow at a speed of x miles per hour. According to the information given, the time the light is yellow (Y) is 1 second more than 0.05 times the speed limit (x). We can write this as:
Y = 0.05x + 1
In this equation:
Y represents the length of time the light is yellow in seconds.
x represents the speed limit in miles per hour.
The equation shows that the time the light is yellow increases linearly with the speed limit, with an additional 1-second buffer.
Answer:
d 34
Step-by-step explanation:
If M is the midpoint, then
AM = MB
4x+18 = 3x+22
Subtract 3x from each side
4x-3x+18 = 3x-3x+22
x+18 = 22
Subtract 18 from each side
x+18-18 = 22-18
x = 4
But we need to find BM
BM = 3x+22
= 3(4)+22
12+22
34
