Try this:  Add up the given widths of the first 3 bookcases, in cm.  This will be a constant.  Now write "-2w" after that sum, to represent two more bookcases of unknown widths w.  Finally, use the inequality symbol (less than or equal to) and the given wall length to complete this inequality.  

Solve it for w, writing your answer as another inequality.

Write an equation of the line in standard form.
Andreyy89

Answer:

Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:

to switch into y=mx+b form do this:

3x-y=5

-y=5-3x

y=-5+3x

y=3x+(-5)

2y-15x=8

2y=8+15x

y=4+7 1/2x

y=7 1/2x+4

THe slope of any line in y=mx+b form is m. Therefore in this equation:

y=3x+(-5)     3 is the slope

The y intercept of any line is the +b:

y=7 1/2x+4 -therefore 4 in this equation is our y intercept.

Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)

since 3 is our slope and 4 is our y intercept the equatuon is :

y=3x+4

NOw all we need to do is move this into standard form:

y=3x+4

-3x+y=4

-3x+y=4 is your final answer

-hope this helped

A used book store will trade 2 of its books for 3 of yours. If Val brings in 18 books to trade, how many books can she get from
Shalnov [3]
You need to set it up as a fraction and make the fractions equal each other. 
2/3 (2 of their books for 3 of yours)
x/18 (x amount of their books for 18 of yours)
(2/3)=(x/18)
multiply both sides by 18 
and you get 
36/3 which reduces to 12

so your answer is 12

Semmy [17]
I believe it should be 4. Because a trend line should be a line that shows the trend haha so it should be equal. Not sure if that makes sense sorry if I didnt explain it well.
