PLEASE HELPPPP ME!!!!!

Mathematics
1 answer:
eimsori [14]3 years ago
4 0

Answer:

Problem 1: No

Problem 2: Yes

Step-by-step explanation:

Problem 1:

{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}

This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.

Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.

Problem 2:

{(0, 2), (3, 4), (-3, -2), (2, 4)}

In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.

Answer:

C

Step-by-step explanation:

The percent markup is basically how much it is MORE than the original.

First, we need to find how much the selling price is more than cost.

Cost = 22.99

Selling Price = 36.99

Markup = 36.99 - 22.99 = $14

How much is the markup, we just found, with respect to cost? That is the markup divided by cost, multiplied by 100 [to convert to percentage]. Shown below:

\frac{14}{22.99}*100=60.9

So, the percent markup = 60.9%

Answer choice C is right.

Do 50 minus 17.97 then take that answer and subtract 25.49 and divide that answer by 3 which equals $2.18. $2.18 is the answer
