Proofs are... well... just that. They are your proof for why a certain property works or what you did to show your work. So essentially, you just do math like normal, a proof is showing what you did and why it works.
Answer:
Correct choice is D. 
.
Step-by-step explanation:
pick any two points from the table say (0,3) and (1,2)
Now we we can use both points to find the equation of line.
slope 
now plug slope m=-1 and any point say (0,3) into point slope formula
Hence correct choice is D. .
1st let's calculate the decreasing rate & let V₁ be the initial value & V₂ the final's
we know that V₂=V₁.e^(r,t) where r=rate & t-time (& e=2.718)
After t= 2 years we can write the following formula
2350,000=240,000.e^(2r)==> 235,000/240000 = e^(2r) =>47/48=e^(2r)
ln(47/48)=2rlne==> ln(47/48)=2rlne=2r (since lne =1)
r= ln(47/48)/2==>r=-0.0210534/2 =-0.01052 ==> (r=-0.01052)
1) Determine when the value of the home will be 90% of its original value.
90% of 240000 =216,000
Now let's apply the formula
216,000=240,000,e^(-0.01052t), the unknown is t. Solving it by logarithm it will give t=10 years
1.a) Would the equation be set up like so: V=240e^.09t? NON, in any case if you solve it will find t=1 year
2)Determine the rate at which the value of the home is decreasing one year after : Already calculated above :(r=-0.01052)
3)The relative rate of change : it's r = -0.01052
i converted them to decimal
-70% = -0.70
Explanation: Every time you need to change percentage to decimal, move the decimal 2 times to the left.
0.34 = 0.34
Explanation: It stays the same because it is already in decimal form.
-2/5 = -0.40
Explanation: you divide with a calculator -2 divided by 5 and that is- 0.40 or you can change the denominator to 100 which you multiply the numerator and denominator by 20: 5*20=100 and -2*20=40 then -40/100 is -0.40
0.96% = 0.0096
Explanation: Every time you need to change percentage to decimal, move the decimal 2 times to the left.
-0.70, 0.34, -0.40, 0.0096
least to greatest:
-0.70, -0.40, 0.0096. 0.34
