No, it is a linear function.

Step-by-step explanation:

Let's select values for X, and find the corresponding Y values:

X = -3, Y = 8.5

X = -2, Y = 7

X = -1, Y = 5.5

X = 0, Y = 4

X = 1, Y = 2.5

X = 2, Y = 1

X = 3, Y = -0.5

So our coordinates are:

(-3, 8.5) ; (-2, 7) ; (-1, 5.5) ; (0, 4) ; (1, 2.5) ; (2, 1) and (3, 0.5)

Graph these on a chart to visualize:

(In picture)

We can see that this is a decreasing linear function, <em>not</em> quadratic. Quadratic functions create a symmetrical curve, which this is not.

A store marked up the prices p of its merchandise by 11%. The marked-up prices of the merchandise can be written as 1.11p. Which
Zina [86]

Answer:

P(1+r) = p(1+0.11)= p+0.11p=1.11p

Step-by-step explanation:

The merchandise is marked up 11%. This means you pay 100% of the price plus 11%. We can represent that as (1+r) where r is the percent marked above. For 11%, this expression would be 1+0.11. We multiply that by the price p. p(1+0.11). This simplifies to p+0.11p. We can further simplify it to 1.11p.

Four students are competing in a race. In how many different combinations could the four students place in the race?
VMariaS [17]

"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.

If 4 students are competing, then the race has

4! = 4 • 3 • 2 • 1 = 24

possible outcomes.
