Find the slope of the line(s) passing through the given points. Then tell whether the line(s) rises, falls, is horizontal, or is

bonufazy [111]

Answer:

21) falls

22) vertical

23) rises

24) rises

25) falls

26) horizontal

27) rises

28) horizontal

29) falls

Step-by-step explanation:

We shall use the slope formula $m=\frac{y_2-y_1}{x_2-x_1}$ to calculate the slopes of the line passing through each pair of point.

21: (3,1), (2,6)

The slope is $m=\frac{6-1}{2-3}$

$\implies m=\frac{5}{-1}=-5$ .

A negative slope means this line falls

22) (-2,5), (-2,4)

The slope is $m=\frac{4-5}{-2- -2}=\frac{-1}{0}$ = undefined

An undefined slope means this line is vertical

23) The given point is (0,8) (2,10)

The slope is $m=\frac{10-8}{2-0}=\frac{2}{2}=+1$

A positive slope means this line rises

24) The points are (-3,-3), (3,1)

The slope is $m=\frac{1--3}{3--3}=\frac{4}{6}=+\frac{2}{3}$

A positive slope means this line rises

25) The points are: (5,0) (6,-2)

Slope: $m=\frac{-2-0}{6-5}=\frac{-2}{1}=-2$

A negative slope means this line falls

26) The points are (-2,-8) , (5,-8).

Slope: $m=\frac{-8--8}{5--2}=\frac{0}{7}=0$

A zero slope means this line is horizontal

27) The points are: (-1,2) , (5,3)

Slope: $m=\frac{3-2}{5--1}=+\frac{1}{6}$

A positive slope means this line rises

28) The points are: $(\frac{1}{2},4)$ , (-1,4)

Slope: $m=\frac{4-4}{-1-\frac{1}{2}}=\frac{0}{\frac{1}{2}}=0$

A zero slope means the line is horizontal

29) The points are: $(4,\frac{1}{2}), (5,\frac{1}{4})$

Slope: $m=\frac{\frac{1}{4}-\frac{1}{2}}{5-4}=-\frac{1}{4}$

A negative slope means this line falls.

Tina covers the floor of a room with carpeting. She uses carpet squares that measure one foot on each side. How many carpet squa

gizmo_the_mogwai [7]

Answer:

She need 96 square feet carpet to cover the room.

Step-by-step explanation:

Given:

Tina covers the floor of a room with carpeting. She uses carpet squares that measure one foot on each side.

Now, to find carpet squares does she need to cover a room that 8 feet wide by 12 feet long.

So, the dimensions of room are:

Length = 12 feet.

Width = 8 feet.

Now, getting the area by putting formula:

Area of room = Length × width

$Area\ of\ room = 12\times 8$

$Area\ of\ room=96\ square\ feet.$

Therefore, she need 96 square feet carpet to cover the room.

$450 per week earns you $450 total per week, for $23,400 total
$115 per week earns you that plus 9.5% of $125,000, which is $11,875, plus $5,980 which is $17,855 total
There is a $5,545 difference, making the $450 a week a better deal
