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

Round 855.788 to the nearest tenth
kykrilka [37]

Answer:

855.8

Step-by-step explanation:

hundreds  tens   ones  .  tenths  hundredths   thousandths

8                   5        5     .     7             8                         8

We are rounding to the nearest tenth, so we look at the next number which is 8.  8>= 5 so we will round the 7 up

855.788 rounds to 855.8

I need help. i don’t understand this question .
user100 [1]

So the question is asking to solve for y

You know RS=7y-4

You know ST=y+5

You know RT=28

RS+ST=RT as shown in the diagram, This means that you can use that equation and replace RS,ST, and RT with what you know they are equal too. So you end up with the equation:

(7y-4)+(y+5)=28, Now you have to solve for y

7y-4+y+5=28

8y+1=28

8y=27

y=3.375
