Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowa
Fudgin [204]
7.50h + 0.20s + 40

variable : a letter subbed in for an unknown number : s and h
coefficient : the number multiplied by the variable : 7.50 and 0.20
constant : just a lone number, no variable attached : 40

Corrine works for 25 hrs and sells 300......h = 25, s = 300
7.50h + 0.20s + 40
7.50(25) + 0.20(300) + 40 =
187.50 + 60 + 40 =
287.50 <===

if she gets a raise and earns 9 per hr...
the coefficient would change from 7.50 per hr to 9.00 per hr. because her pay rate has changed.
the new equation would then be : 9h + 0.20s + 40

2. Given f(x) = 6(8 - x)+5
son4ous [18]

Answer:

a) Find the value of the function when x  = -2

b) we get f(-2)=65

Step-by-step explanation:

We are given the function f(x)=6(8-x)+5

a) What does the notation f(-2) mean?

The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x  = -2

b) What is the value of f(-2) ?

We need to find the value of f(-2)

f(x)=6(8-x)+5

Put x = -2

f(-2)=6(8-(-2))+5\\f(-2)=6(8+2)+5\\f(-2)=6(10)+5\\f(-2)=60+5\\f(-2)=65

So, we get f(-2)=65

Harper wants to put wood shavings in her rabbit's cage. The floor of the cage measure 4 feet long. One bag of shaving covers 5 s
Ronch [10]

Answer:

0.16 bags

Step-by-step explanation:

Given that:

the floor of the rabbit's cage is 4 feet long and one bag of shaving covers 5² ft.

the floor of the rabbit's cage which is 4ft = 25 ft for one bag of wood shaving

to determine the amount of wood shaving Harper needs to buy  to cover 4 feet of her rabbit's cage ; we have:

x bags = 4 feet

1 bag = 25 feet

25*x = 4*1 \\ \\ x = \frac{4*1}{25}

x = 0.16 bags of wood shaving is needed to cover the floor of of the rabbit's cage that measures 4 feet long.
