Answer:

Step-by-step explanation:

"One number is eight less than a second number."

x = y-8

"Twice the first is 12 more than 4 times the second."

2x = 4y+12

substitution

2(y-8) = 4y + 12

2y - 16 = 4y + 12

2y = -28

y = -14

x = y-8 = -22

muminat

Answer:

Yes, because the linear function x - y = 5 is a function

Step-by-step explanation:

x - y = 5 can look like y = x - 5 with slope 1 and y-intercept -5

so this is a function which makes set K a function.
