Answer:
It is a one-to-one function. C is the correct answer
Step-by-step explanation:
Since no x values are repeated on the Y axis, it is a one-to-one function. Option C is correct
Answer:
0.5
Step-by-step explanation:
First you solve for y.
5x+ y= 12 so Y= 12-5x
And plug it into the next equation
3x- 3(12-5x) = 18
Distribute
3x-36+15x=18
Add 36 to both sides
3x+ 15x= 54
18x= 54 ... divide
x= 3
And you can plug in x to solve for Y
5(3) + y = 12
15+ y = 12 ...subtract 15 from both sides
y= -3
