Answer:
D
Step-by-step explanation:
Consider the equation:

Use distributive property in both sides:

Separate terms with x into the left part and terms without x into the right part:

Since you get true equality 0 = 0, the equation is true for all real values of x. So, the equation has infinitely many solutions.
Answer:
x is all real numbers
Step-by-step explanation:
The domain is the values for the inputs

Answer:
1. $20280
2. 117 h
Step-by-step explanation:
1.
to know the value of the car we have to add all the monthly payments with the $ 3000 that she paid at the beginning
x = car value
x = $3000 + 48 * $360
x = $3000 + $17280
x = $20280
The total cost of the car is $20280
2.
To know how many hours I work in total we have to add the hours I work in each day 5 times with the 57 hours I work the following week
x = hours that work in all
x = 5 * 12 + 57
x = 60 + 57
x = 117
work for 117 hours in all
Step-by-step explanation:
Solving
2x + 6 = 4x - 4
Bringing like terms on one side
6 + 4 = 4x - 2x
10 = 2x
10 / 2 = x
5 = x
