Answer:

The number of hours must be greater than 9 to make a Company B a better deal

Step-by-step explanation:

Let

x ----> the number of hours

y ----> the total charge in dollars

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

Company A

The slope is equal to $m=\$10\ per\ hour$

The y-intercept is equal to $b=\$80$

The linear equation is equal to

$y=10x+80$ -----> equation A

Company B

The slope is equal to $m=\$5\ per\ hour$

The y-intercept is equal to $b=\$125$

The linear equation is equal to

$y=5x+125$ -----> equation B

If a Company B is a better deal

then

$5x+125 < 10x+80$

solve for x

$125-80 < 10x-5x$

$45 < 5x$

$9 < x$

Rewrite

$x> 9\ hours$

therefore

The number of hours must be greater than 9 to make a Company B a better deal

Which of these points are on a line that has a slope of -3?

Ira Lisetskai [31]

Simple....

using the formula $\frac{ y_{1}- y_{2} }{ x_{1}- x_{2} }$ to find slope....

1.) (9,2)(4,3)

$\frac{2-3}{9-4}= -\frac{1}{5}$ (No)

2.) (9,2)(3,4)

$\frac{2-4}{9-3} = -\frac{2}{6} =- \frac{1}{3}$ (No)

3.) (2,9)(3,4)

$\frac{9-4}{2-3} = \frac{5}{-1} =-5$ (No)

4.) (2,9)(4,3)

$\frac{9-3}{2-4} = \frac{6}{-2} =-3$ (YES!)

Thus, your answer.

Find the distance between the points (-7,-6) and (5,-6) .

PilotLPTM [1.2K]

Answer:

12 units

Step-by-step explanation:

We are given these two points, (-7,-6) and (5,-6), and we are to find the distance between them.

We know the formula for finding the distance between two points:

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

So putting in the values of the given coordinates in the above formula to get:

Distance = $\sqrt{(5-(-7))^2+(-6-(-6))^2}$ = $\sqrt{144 + 0} =12$

Therefore, the distance between the two given points is 12 units.
