2 x 7, unless there’s options you have to choose from. 6-(-8)=14, so pretty much anything that equals to 14

Hannah is setting up chairs for the class play. The room has 20 chairs. What are the different ways she can arrange the chairs i
andrezito [222]

Answer:

Have them 4 by 5.

Step-by-step explanation:

If you she but 5 chairs in a row, then 3 on the side of the chairs. That would create a backward "L" type of shape.

For example, (The "o" is a chair)

OOOOO

O

O

O

As you see the the top are the 5 chairs, then side are are the 4 chairs.

Then, you will do the exact same thing  but on the opposite side.

Here is the next example.

OOOOOO

O            O

O            O

O            O

OOOOOO

Basically, arranging the chairs 4x5, it would make a rectangle.

Suppose M is the midpoint of line FG. Use the given information to find the missing measure or value.
tangare [24]
If it is the midpoint, then FG= FM+MG


Also, this means that they are of equal lenght, so

FM=MG
<span>5y + 13= 5-3y
5y+3y=5+13
8y=18
y=\frac{18}{8}=2.25
</span>
which means that the two halves are equal to 5y+13=5*2.25+13=24.25

and FG is double the lenght:

24.25*2=49

Which of the following is equation of a line that passes through (-2,1) and (-4,-3)?​
ladessa [460]

Answer:

<h2>y = 2x + 5</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

=======================================

We have the points (-2, 1) and (-4, -3). Substitute:

m=\dfrac{-3-1}{-4-(-2)}=\dfrac{-4}{-2}=2

y=2x+b

Put the coordinates of the point (-2, 1) to the equation:

1=2(-2)+b

1=-4+b           <em>add 4 to both sides</em>

5=b\to b=5

Finally:

y=2x+5
