Answer:

Yes, it is. Functions can only have one output (y) for each input (x). Furthermore, this means each x value will only have one y passing through it. Thus if we plot it on a graph and it passes through a horizontal line more than once, it is not a function. This is called the vertical line test.

The chess club has 50 members. They want to raise $680 for a trip to a competition. The school will give $130 How much must each

Setler79 [48]

So what they need to rais is what the school doesn't give them
so to find that subtract what the school gives them from how much they need
need=680
given=130
680-130=550
they need to raise 550

if each member raises the same amount we fid that by doing
total divided by number of members
total=550
number o fmembers=50
550/50=11
each must raise $11
