Answer:
<u>A function is a mathematical relationship where all inputs must have exactly one output. If there is more then one output for one input, then the relationship is not a function.</u>
x is most of the time the input and y the output for an equation:
y = 2x
of course the input and output could be any variable.
Step-by-step explanation:
Have a nice day!
y=2x+4
-4 -4

-4/2 2x/2
-2=x

Alto earned $ 225 and Sheryl earned $ 250.
Given that Alto and Sheryl both worked hard over the summer, and together they earned a total of $ 475, and Sheryl earned $ 25 more than Alto, the following calculation must be performed to determine how much each one earned:
- S = A + 25
- A = A
- A + 25 + A = 475
- 2A = 475 - 25
- A = 450/2
- A = 225
- S = 225 + 25 = 250
Therefore, Alto earned $ 225 and Sheryl earned $ 250.
