Considering the one time deposit and monthly went rent the equation y equals 1200+400x can be used to represent why the total cost of renting an apartment for x months what is the amount of the deposit

The trick with this problem is that there is no trick - there's no math involved at all, just wordplay. The key is in one-time deposit; what you're looking for isn't a recurring fee, but rather a constant. Now, an equation is made up of three things:

In this case, what you're looking for is the constant in the equation; a value that doesn't change when any variable changes.

The only number in your question that fits the bill is 1200$, since it's a one-time, unchanging value. y is the total amount paid and x represents the months, which are both variables; 400 is tied to x, so it also changes based on months.

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
