You are given the dollar value of a product in 2012 and the rate at which the value of the product is expected to change during
Ray Of Light [21]

Answer:

V=r*t+D-2*r

with

V= dollar value of the product

r= value's rate of change

t= time in years (where t=0 represents 2010)

D= dollar value of product in 2012

Step-by-step explanation:

A linear equation for V in terms of t will have the following form

V=r*t+C <em>(equation 1)</em>

where r will be the rate at which the value of the value of product is expected to change, V is the dollar value of the product at the year t (being t=0 for 2010) and C is a constant number which we should be able to find knowing the value of V at some point in time.

Let's call D the dollar value of the product in 2012, we can replace this value in <em>the equation 1</em> in order to find C

V=r*t+C <em>(equation 1)</em>

D=r*2+C

C=D-2*r

So the final equation would be

V=r*t+D-2*r

with

V= dollar value of the product

r= value's rate of change

t= time in years (where t=0 represents 2010)

D= dollar value of product in 2012

Which theorem would be used to write 4x+4=92 in the diagram below?
yKpoI14uk [10]

Answer: C) Alternate interior angles

The blue angles marked are inside the parallel lines, so they are considered interior. They are on alternating sides of the transversal line. The angles are only congruent when the lines are parallel.
