Determine if the set of ordered pairs represents a function. Explain why or why not. (2 points)

Nutka1998 [239]

Answer: Depends on the orders pairs

Step-by-step explanation: You didn’t include the ordered pairs so I’ll just do an example.

(1,5). (2,11). And(6,13) Theese orders pairs represent a function because, there are no repeating X values.

(2,5) (2,10) and (5,45)

Theese ordered pairs do NOT represent a function because, the X values repeat.

A function can be linear and nonlinear, they can have repeating Y values but NO repeating X values.

A trick for this is to put a piece of paper and cover sections and see if your line “turns back”.

Write the negation of: If we lose electricity, then the data will be lost.

Aleks04 [339]

Step-by-step explanation:

Consider the provided statement.

If we lose electricity, then the data will be lost.

We are need to write the negation of the above statement.

First divide the whole statement in two parts

Let us consider p = We lose electricity and q = The data will be lost.

The symbol use for negation is tilde $\sim$

$\sim(p\rightarrow q)$

$p\wedge \sim q$

Represent T for true and F for False.

The required table is shown below:

p q $(p\wedge \sim q)$

F F F

F T F

T F T

T T F

Hence the required table is shown above.

Ratling [72]

The regular monthly fee without coupon is $ 50

Solution:

Given that, Chelsey wants to join a fitness club

With the coupon, her total cost for the 6 months is $225

Therefore,

With coupon cost for 6 months = 225

She has a coupon that will give her $12.50 off the monthly rate for the first 6 months

Therefore,

For 6 months, coupon gives a off of,

$12.50 \times 6 = 75$

Therefore,

Without coupon cost = 225 + 75 = 300

Thus the regular monthly fee without coupon is:

$\frac{300}{\text{ 6 months }} = 50$

Thus regular monthly fee without coupon is $ 50
