Yes it is a function Bc the x values don’t repeat
The answer is A
start by isolating the y variable
the rest of the work is shown here

5 - 1.25 = 3.75
Melody’s mom pays her sister $3.75 for emptying the dishwasher.
The numbers are 3 and 7
Step-by-step explanation:
Let the first number be x and the second number be y
Then according to given statement
One number added to three times another number is 24
x+3y=24 Eqn 1
Five times the first number added to three times to other number is 36
5x+3y=36 Eqn 2
Subtracting Equation 1 from equation 2

Dividing both sides by 4

Putting x=3 in equation 1

Dividing both sides by 3

Hence,
The numbers are 3 and 7
