The graph should be discrete, even though often times you will see it graphed as continuous only because the graphing software used might not have the capability of showing discrete dots rather than continuous lines. Basically you can only sell whole tickets , so that makes the value of x integers .
the fact that y is not an integer is irrelevant.
in fact, y is also restricted in the values it can take.
those values are determined by the factor of 2.50 * x.
when x = 0, y = 0 * 2.50 = 0
when x = 1, y = 1 * 2.50 = 2.50
when x = 2, y = 2 * 2.50 = 5.00
when x = 3, y = 3 * 2.50 = 7.50
when x = 4, y = 4 * 2.50 = 9.00
the values of y can only be multiplies of 2.50.
the equation used is y = 2.50 * x
x is the number of tickets sold.

Step-by-step explanation:
<u>Alternating Sequences</u>
A sequence whose terms alternate in the sign is called an alternating sequence.
The given sequence consists of the numbers -6 and 6 in infinite alternation.
Such sequences can be expressed as equations of the form

Where a is the constant absolute value of each term and m is an expression adequately arranged to reproduce the alternation of signs.
Since the sign is minus for odd terms, and plus for even terms, m=n is a good expression for m. Thus:

Answer:
-4
Step-by-step explanation:
i just did it on edge and got it right
Answer:
20/4
Step-by-step explanation:
Because that would mean 20 divided by 4 which wouldn't accumulate to 80
Y=12x+30
I think this is correct. But please don't hold me to it:) Hope I helped!
