Someone please help me with this algebra problem

Mathematics
1 answer:
nevsk [136]3 years ago
4 0

Answer:

$110

Step-by-step explanation:

We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:

\frac{y_{2} -y_{1} }{x_{2}- x_{1} }

We can substitute the points given, (2, 480) and (5, 150) and simplify:

\frac{150-480}{5-2} =\frac{-330}{3} = -110

We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110

If you multiply an inequality by a negative number _____.
sergeinik [125]

Answer:

<h2>A. Switch the inequality sign</h2>

Step-by-step explanation:

When multiplying, you must switch the inequality sign. This is also true when dividing.

EXAMPLE 1:

-4r < -21

Note: We reversed the inequality sign when we divided by -4

r > 5 1/4

EXAMPLE 2:

x/-5 <u>></u> 7

Note: We reversed the inequality sign when we multiplied by -5

x <u><</u> -35
