The value of a home in 2015 was $400,000. Its value has been doubling each decade.

a. If v is the value of the home, in dollars, write an equation for v in terms of d, the
number of decades since 2015.

b. What is v when. d =-1? What does this value mean?

c. What is v when d = -3? What does this value mean?

step-by-stp

the correct answer is the section c

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
