Answer:
Two x's can have the same y, but an x cannot have different y's. For example, [(2,3)(-2,4)(3,3)(5,18)] is a function because all of the x's have a specific y, and there is not more than one y to an x. However, [(2,3)(-3,7)(2,-4)] is not a function because one of the x's has more than one y.
Step-by-step explanation:
(hope this helps-you can just put the first sentence...the rest is kinda wordy :P)
#2 is 35°C (just plug in 95 to the formula)
#3:
in the left column are:
(8x-(6+y))
(3/4)w+x^2
in the right column are:
y^2-0.5w
w/4+3(x+y)
to solve you just plug in to the formula
The answer is 30 because u have to round 73 to 70 and 13 to 10 and in the middle of 10and 70 is 30
The answer is unnecessary
