The elevator at the local mall has a weight limit of 1,800 pounds and requires that the maximum person allowance be no more than nine people.
a. let x represent the number of people. write an inequality to describe the maximum allowance of people allowed in the elevator at one time.
b. draw a number line diagram to represent all possible solutions to part (a).
c. let w represent the amount of weight, in pounds. write an inequality to describe the maximum weight allowance in the elevator at one time.
d. draw a number line diagram to represent all possible solutions to part (c).

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
