.
<h3>What is a function?</h3>
An expression, rule, or law that describes a relationship between one variable (independent variable) and another variable (dependent variable) exists named a function.
Let the functions be 
and 
Adding both of the equations, we get
simplifying both of the equations we get
Therefore, the function R(x) + S(x) exists given by .

Answer:
10 months. Each plan will save 800 dollars.
Step-by-step explanation:
500 + 30x = y
300 + 50x = y
You want the months to give the same amount of money. The x has to be the same for both
500 + 30x = 300 + 50x Subtract 300 from both sides
500 - 300 + 30x = 50x Combine
200 + 30x = 50x Subtract 30x from both sides
200 = 50x - 30x Combine
200 = 20x Divide by 20
x = 10
So in 10 months time the amounts will be the same. How much will there be?
500 + 30*10 = 500 + 300 = 800
300 + 50*10 = 300 + 500 = 800
Answer:
1/3
Step-by-step explanation:
You can rewrite the equation like so:
2/3 + (-1/3)
2/3 - 1/3
The denominators are the same so you don't need to worry about that:
2/3 - 1/3 = 1/3
1/3 is your answer
Hope this helps!
