If you graph a system of linear inequalities that have no overlap, what can you determine from the slopes of the inequalities?

NISA [10]

I have found the options elsewhere and they are as follows:

the slopes must be positive

the slopes must be negative

their slopes are equal

the slopes are opposite reciprocals.

From the choices, I think the correct answer would that their slopes are equal since they are parallel lines and never intersect.

Fanny Mendelssohn manages all the magazines and paperback books at a local grocery store. She prices many paperbacks to sell at

Answer:

The markup rate is 51% on the cost

Step-by-step explanation:

Price of book = 7.99

Cost to the store = 5.29

The markup rate is a term used to figure what percentage is added on to the cost of the item to find its selling price.

If we subtract cost from the price we will know how much is added to actual cost: 7.99 - 5.29 = 2.7

$Markup rate = \frac{added value}{cost}$

$Markup rate = \frac{2.7}{5.29} = 0.51$

Markup rate is 0.51*100 = 51%
