Answer:
functions cant have the same x vaule
im not sure which is a "set" since all the numbers are all under the same line
(3,4) (4,5) (5,6) (6,7) would be function
(1,6) (1,7) (3,4) (2,8) wouldnt be a function because of the 1
I honestly don’t know either
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
