Answer:
your question is not complete or should I say not correct ☺️
It is a function, so yes ig
12 x $3 = 36
if K gave the caashier 2, $20 bills.
K will get $4 in change
Are these simultaneous questions or like seperate ones?
Simultaneous:
4x -3(7x-4) = 12
4x - 21x + 12 = 12
-17x = 0
X = 0
Therefore y = -4
***
If it's a graph
x int: (3,0)
Y int: (0, -4)
Um idk if that's the answers you wanted but I hope it helped somehow??
