For this case we have that if "y" varies directly with "x", we can propose:

y = kx

Where "k" represents the constant of proportionality.

According to the data:

180 = kn\\n = k5

We substitute the second equation in the first:

180 = k * k5\\180 = 5k ^ 2\\k ^ 2 = \frac {180} {5}\\k ^ 2 = 36

We apply root:

k = \pm \sqrt {36}\\k = \pm6

If k = 6, thenn = 6 * 5 = 30

Answer:

n = 30

Y>1 and y>x on a graph
zlopas [31]

So,

y>1\wedge y>x

1. Graph each inequality separately.

2. Choose a test point to determine which side of the line needs to be shaded.

3. The solution to the system will be the area where the shadings from each inequality overlap one another (purple area)

As for the system of inequalities we say it's unbounded.

In 1970, the median home value was $20,000. By 2020, the median home value was $320,000. What is the percent increase in home va
ArbitrLikvidat [17]

Answer:

1500%

Step-by-step explanation:

The formula for Percentage increase is

Increase/ Initial Amount × 100

Increase = Current Amount - Initial Amount

Increase = $320,000 - $20,000

Increase = $300,000

Percentage Increase =

$300,000/$20,000 × 100

= 1500%

The percent increase in home value in those 50 years is 1500%
