The board of trustees for a school is considering a tuition increase. one faction in the board supports plan a, which involves raising the tuition 9% this year and 8% the next. others want plan b, which has the 8% raise this year and the 9% next year. some say it doesn't matter because in either case, the tuition is the same in the second year. does it make any difference as to which plan is implemented?

It doesn't matter which plan is implemented. In either case, the tuition will be same.

Step-by-step explanation:

Let current tuition fee be  

Plan A:

Raise 9% first year:

Raise 8% 2nd year:

Plan B:

Raise 8% first year:

Raise 9% 2nd year:

As we can see, the amount is same for BOTH THE PLANS. So it doesn't matter which plan in implemented.

the range of a function is the range of y-values for which it is defined, or exists. given that we are only looking at the y-values, we can already discount the first two answers as they deal with the domain of the function (range of x-values).

now, what we need to do is find the smallest and highest y-values for which the function is defined. if you'd like, you could take a ruler and start at the very bottom of the graph, find the lowest point, then move the ruler higher and higher until you reach the highest point. doing so either in your head or with an actual ruler, we can see that the lowest y-value is -5 and the highest y-value is -1.

the question now remains as to whether they are included in the range (fourth answer) or excluded (third answer). the key here is to recognise whether they are marked with an open or a closed circle. since both (-2, -5) and (2, -1) are marked with a closed circle, they are points that exist on the graph and are thus included in the range (note that if they were marked with an open circle like (4, -2) then that would signify that there is a break in the graph at that point).

thus, the fourth answer, (y | -5 ≤ y ≤ -1), is correct.

also note that usually it is good practice to scan your eye inbetween the highest and lowest point for any breaks in the graph - we do have one here at (4, -2), however -2 is still included in the range because there is another point that is included in the graph with the same y-value, ie. point (1, -2).

i hope that but if you require any further explanation don't hesitate to comment below.

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week
