Answer:
The difference in the populations of the cities when t=4 is 25,800.
Step-by-step explanation:
Given equations each of the city:
-150t+50,000
and
50t+75,000
To find the difference between the population when t=4, we first have to solve both equation when t=4.
For both equations, substitute 4 into t:
-150(4) + 50,000 = 49,400
50(4) + 75,000 = 75,200
Now subtract 49,400 from 75,200 and you get 25,800.
The difference in the populations of the cities when t=4 is 25,800.
Answer:
4x - 7
Step-by-step explanation:
Answer:
x = 4 and x = 6
Step-by-step explanation:
There are two solutions to an absolute value equation.
If |x - 5| = 1, then
x - 5 = -1 and
x - 5 = +1.
1. Solve x - 5 = -1
Add 5 to each side.
x = 4
2. Solve x - 5 = 1
Add 5 to each side.
x = 6
The solutions are x = 4 and x = 6.
3. Number line
The number line would have markers at 4 and 6.
It should look like the image below.
