Answer:

The slope is -2/3

Step-by-step explanation:

It is recommended to solve for 'y' variable the equation given, this means, leave the 'y' variable alone in one side of the equation. Doing that, leaves us the following:

$y=\frac{-2}{3}x +\frac{1}{3}$

This is the general equation of a line: $y=mx+b$ where 'm' is the slope (by comparison), thus We have the desired result

e-lub [12.9K]

Answer:

200 Recyclables Items

Step-by-step explanation:

You can get the common ratio by dividing 150/3 = 50

So 50 Recyclables Items per minute.

Now multiply 4 by 150 = > 200 Recyclables Items.

Hope this helps!

Explain why f(x) = x^2-x-6/x^2-9 is not continuous at x = 3.

iren [92.7K]

Answer:

See Explanation

Step-by-step explanation:

Given

$f(x) = \frac{x^2 - x -6}{x^2 - 9}$

Required

Why is the function not continuous at x = 3

First substitute 3 for x at the denominator

$f(x) = \frac{x^2 - x -6}{x^2 - 9}$

Factorize the numerator and the denominator

$f(x) = \frac{x^2 - 3x+2x -6}{x^2 - 3^2}$

$f(x) = \frac{x(x - 3)+2(x -3)}{(x - 3)(x+3)}$

$f(x) = \frac{(x+2)(x - 3)}{(x - 3)(x+3)}$

Divide the numerator and denominator by (x - 3)

$f(x) = \frac{x+2}{x+3}$

Substitute 3 for x

$f(3) = \frac{3+2}{3+3}$

$f(3) = \frac{5}{6}$

Because $f(x) = \frac{x^2 - x -6}{x^2 - 9}$ is defined when x = 3;

Then the function is continuous
