Remember
a/b time b/a=1
and
a/b times b=a

and when working with inequalities (> < <u>> <</u>)
flip the sign when dividding or multiplying by a negative number
so < becomes >, <u>></u> becomes <u><</u>

(3/5)e<u>></u>9
multiply both sides by 5/3
e<u>></u>45/3
e<u>></u>15


x/-6<u>></u>5
multiply both sides by -6 don't forget to flip sign
x<u><</u>-30

A ceramics store manufactures and sells coffee mugs. The revenue r(x) from the sale of x coffee mugs is given by r(x)-6.5x. Supp
KonstantinChe [14]

Answer:

Step-by-step explanation:

The revenue r(x) from the sale of x coffee mugs is given by

r(x) = 6.5x

the function for the cost of manufacturing x coffee mugs is c(x)= 0.75x + 1850.

Profit = Revenue - cost

P(x) = r(x) - c(x)

P(x) = 6.5x - (0.75x + 1850)

P(x) = 6.5x - 0.75x - 1850

P(x) = 5.75x - 1850

A) profit when x = 500 is

P = 5.75 × 500 - 1850

P = 2875 - 1850

P = 1025

profit when x = 1000 is

P = 5.75 × 1000 - 1850

P = 5750 - 1850

P = 3900

profit when x = 5000 is

P = 5.75 × 5000 - 1850

P = 28750 - 1850

P = 26900

B) The profit function would be

P(x) = r(x) - c(x)

P(x) = 5.75x - 1850

On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277at 3:00
Elena L [17]

<u>Given</u>:

Let time be the independent variable.

Let mile marker be the dependent variable.

On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277 at 3:00 and Mr. Morales was driving at a constant speed.

The coordinates of the points on this line are (1,123) and (3,277)

We need to determine the slope of the line.

<u>Slope of the line:</u>

The slope of the line can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the points (1,123) and (3,277) in the above formula, we get;

m=\frac{277-123}{3-2}

m=\frac{154}{1}

m=154

Therefore, the value of the slope of this line is 154.
