1. use the formula d=rt to find the average speed of driving 330 miles in 5
hours.
= -3(6x + 9)
a school drama club is putting on a play. its expenses will be $300. use the formula p= nt-e,
(pls profit, n is number of tickets, t is price per ticket, e is expenses) to answer questions 2-5.
2. how many tickets must be sold at $3 each to make $1,500 profit?
5 = 4(x + 3) – 6x
3. if the drama club expects to sell approximately 600 tickets, what should it charge for each
ticket to make $1,800 profit?
= 2x + 4(x-1)
4. if the drama club sells 500 tickets at $2.50 each, what will be its profit?
» number
5. if the drama club expects to sell only 450 tickets at $2.50 each, by how much would it have
to lower expenses to make $1,000 profit?

the answer is 24

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
