Slope intercept form y=mx+b
where m is the slope (rise over run) the slope here is rise (3 over 1)

and b is the y intercept so the point (0,7)
because the line will intercect the y axis where X is zero

Answer :
plot the point given (2,3) and the y intercept (0,7)

then you can connect the two
make sure by double check that the slope is 3.

If it takes 10 seconds for 10 printers to print out 10 pages of paper, how many seconds will it take 50 printers to print out 50

Fed [463]

Lets use the formula $RWT=J$ to solve this, where,

R is the rate
W is the number of workers/things
T is time
J is number of jobs/things

<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -

W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:

$R(10)(10)=10\\R(100)=10\\R=\frac{10}{100}\\R=0.1$

<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use $R=0.1$ (previously found) to figure out T.</em>

<em> $RWT=J\\(0.1)(50)T=50\\5T=50\\T=\frac{50}{5}\\T=10$ </em>

So it will take 10 seconds for 50 printers to print 50 pages.

3. The fish tank shown at right needs to be cleaned. The cleaning product instructions state that three drops should be put in t

sasho [114]

Drops = 27

First, we need to find the volume of the given tank using the following equation

$Volume = Length*Width*Height\\Volume =14*9*10\\Volume =1260\\$

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation

$Drops = 3\frac{Volume}{140} \\Drops = 3\frac{1260}{140} \\Drops = 3(9) \\Drops = 27$

Solve using the elimination method -4x-2y=-18

Softa [21]

Step-by-step explanation:

-4x – 2y= -18

Add 2y to both sides

-4x- 2y+ 2y = -18 + 2y

Simplify

-4x = -18 + 2y

Divide both sides by -4

-4x/-4= -18/-4+ 2y/-4

simplify

x= - -9+y/2
