Answer:

$\boxed {m = -\frac{5}{7}}$

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

First Point: $(x_{1} , y_{1})$

Second Point: $(x_{2}, y_{2})$

-Substitute both points:

First Point: $(5, 11)$

Second Point: $(19, -1)$

$m = \frac{-1 - 11}{19 - 5}$

-Solve for the slope:

$m = \frac{-1 - 11}{19 - 5}$

$m = \frac{-10}{14}$

$\boxed {m = -\frac{5}{7}}$

Therefore, the slope is $-\frac{5}{7}$

Answer:

see below

Step by step explanation

$\because \: revenue = price \times demand \\ \therefore \: r(x) = x.d(x) \\ \therefore \: r(x) =x(200 - 2x) \\\therefore \: r(x) = \boxed{200x - 2 {x}^{2} }$

The sum of two numbers is 19, and their difference is 55. What are the two numbers?

Vilka [71]

Answer:

37 and -18

Step-by-step explanation:

Let one number be x and other y

1 x + 1 y = 19 .............1

1 x -1 y = 55 .............2

Eliminate y

multiply (1)by 1

Multiply (2) by 1

1 x 1 y = 19

1 x + -1 y = 55

Add the two equations

2 x = 74

/ 2

x = 37

plug value of x in (1)

1 x + 1 y = 19

37 + 1 y = 19

1 y = 19 -37

1 y = -18

y = -18

37 and -18
