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

How do I solve this system of equations by substitution? <br> y - 3x = 2, y=(x + 1)^2 - 5
Arada [10]
Hello,

y-3x=2==>x=(y-2)/3
==>(x+1)²=((y-2)/3+1)²=(y+1)²/9

y=(x+1)²-5
==>y=(y²+2y1)/9 -5
==>y²-7y-44=0  ; Δ=7²+4*44=225=15²
==>y=(7+15)/2 or y=(7-15)/2

==>y =11 and x=(11-2)/3=3
 or y=-4  and x=(-4-2)/3=-2

sol={(3,11);(-2,-4)}
