Answer:

Sample response:

Step-by-step explanation:

She would multiply the rate by the years to find the average rise in water levels, or 1.8 times 6.2 = 11.16. To find the difference between the water levels, she would subtract -13.64 from 11.16.

76 19 in ratio simplest form

Nata [24]

Putting the two numbers together in fraction form of a ratio, we have 76/19. We know that something multiplied by 19 will equal to 76.

When we try to multiply 4 and 19 together, we have our nice answer 76. We then replace out values in the original ratio, in which we get the final answer of 4:1, 4/1, or 4 to 1.

Find a linear inequality with the following solution set. Each grid line represents one unit. [asy] size(200); fill((-2,-5)--(5,

kykrilka [37]

The linear inequality of the graph is: -x + 2y + 1 > 0

<h3>How to determine the linear inequality?</h3>

First, we calculate the slope of the dashed line using:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Two points on the graph are:

(1, 0) and (3, 1)

The slope (m) is:

$m = \frac{1 - 0}{3 - 1}$

This gives

m = 0.5

The equation of the line is calculated as:

$y = m(x -x_1) + y_1$

So, we have;

$y = 0.5(x -1) + 0$

This gives

$y = 0.5x -0.5$

Multiply through by 2

$2y = x - 1$

Now, we convert the equation to an inequality.

The line on the graph is a dashed line. This means that the inequality is either > or <.

Also, the upper region of the graph that is shaded means that the inequality is >.

So, the equation becomes

2y > x - 1

Rewrite as:

-x + 2y + 1 > 0

So, the linear inequality is: -x + 2y + 1 > 0
