20. we see that is has a yint of 1
it has a slope of 2/3
y=2/3x+1

21. has a yint of -1
has a sloe of -1
y=-x-1

22. from the center, go 3 units down and plot a point there
from that point, go 4 units up, and 1 unit to the right, put a point there
connect those 2 points wit a line

23. go 2 units up from center
go left and right forever (horizontal line going throug y=2 or (x,2)

24. graph the point (1,-3)
go 2 units up and  1 to right (-1,2) and plot a point, connect the points

25. y=-1/4(x-10)
graph the point (10,0)
go 1 down and 4 to the right (14,-1) and connect the points

use desmos graphing caluclator if yo ar stuck

gizmo_the_mogwai [7]

Answer:

She need <u>96 square feet</u> 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:

<u><em>Area of room = Length × width</em></u>

Area\ of\ room = 12\times 8

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

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

A motorboat takes 5 hours to travel 100mi going upstream. The return trip takes 2 hours going downstream. What is the rate of th
Temka [501]
The boat went 5hours upstream, let's say it has a "still water" speed rate of "b", it went 100miles... however, going upstream is going against the current, let's say the current has a speed rate of "c"

so, when the boat was going up, it wasn't really going "b" fast, it was going " b - c " fast, because the current was eroding speed from it

now, when coming down, the return trip, well the length is the same, so the distance is also 100miles, it only took 2hrs though, because, the boat wasn't coming down  "b" fast, it was coming down " b + c " fast, because the current was adding speed to it, so it came down quicker

now, recall your d = rt, distance = rate * time

\bf \begin{array}{lccclll}&#10;&distance&rate&time\\&#10;&-----&-----&-----\\&#10;upstream&100&b-c&5\\&#10;downstream&100&b+c&2&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;100=(b-c)5\\&#10;\qquad \frac{100}{5}=b-c\\&#10;\qquad 20=b-c\\&#10;\qquad 20+c=\boxed{b}\\&#10;100=(b+c)2\\&#10;\qquad 50=b+c\\&#10;\qquad 50=\boxed{20+c}+c&#10;\end{cases}

solve for "c", to see what's the current's speed

what's "b"?  well 20+c = b

In a programming team of 20 persons, 1/4 are women and 3/4 are men. to obtain a team with 40% women, how many women should be hi
Savatey [412]
This is the concept of algebra, to solve the question we proceed as follows;
the current number of women is:
1/4*20=5 women
the percentage of women is:
1/4*100=25%
therefore for the team to have 40% women, the number of women should be:
40/25*5
=8 women
The answer is 8 women
