Answer:
In year 2026 population of both the states will be same.
Step-by-step explanation:
It has been given in the question that the population y of State A in year x will be represented by the equation
-3x + y = 11,400
⇒ y = 11,400 + 3x --------(1)
Similarly, equation that represents the population for State B is
-138x + y = 8,000
⇒ y = 138x + 8,000 -------(2)
If population y for both the states are equal then
3x + 11,400 = 138x + 8,000
11400 - 8000 = 138x - 3x
135x = 3400
x = 25.19 [After 25 years ]
Since x = 0 represents the population of the states in year 2000
therefore, population y will be same in both the states in year (2000 + 26)
= 2026
Absolute Value Equations are equations that look like this:
I x + 5 I = 15
They have 2 solutions almost all the time. To solve this equation we do this:
x+5=15 x+5=-15
Then you solve them:
x+5=15 x+5=-15
x=15-5 x=-15-5
x=10 x=-20
The solutions would be x=10 and x=-20 .
In some cases, you only have one solution:
I x + 5 I = 0
0 cannot be negative, so we only have one equation to solve:
x+5=0
x=0-5
x=-5
The one solution would be x=-5 .
In some OTHER cases, you have no solution. This happens when the absolute value equation equals to a negative number:
I x + 5 I =-10
Absolute value solutions are always going to end up positive because absolute value turns the number, negative or positive, into a positive.
Hello!You have to multiply 1 1/4 by 30 because each math book is 1 1/4 in. thick, and 30 books is 1 1/4 by 30. First change 30 and 1 1/4 to an improper fraction.
