Answer:
C=(x – 1)(x2 + x + 1)
E=(x + 4)(x2 – 4x + 16)
Answer: 
Step-by-step explanation:
Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:
Month 1:
Gloria talked on her cell phone for 
. So, she had to buy 2 packages of 
for 
each package.
Hence:
Month 2:
Gloria talked on her cell phone for 
. So, she had to buy again 2 packages of for each package.
Hence:
Month 3:
Gloria talked on her cell phone for 
. So, she had to buy 3 packages of for each package.
Hence:
Then, if we take the total Gloria had to pay for the frist three months, we have:
Point slope eqaution is
y-y1=m(x-x1)---------equation1
find m slope=y2-y1/x2-x1
m=-3+1/3+4=-2/7
so put those all values in eqaution 1
<span>(x1, y1) as (-4, -1).</span>
y+1= - 2/7(x+4)
Given:
Initial value = 25,000
depreciation = 15% per annum based on net book value
Net book value = 25,000 (1 - 0.15)^t
where t is the number of years
NBV = 25,000 (0.85)^5
NBV = 25,000 (0.4437)
NBV = 11,092.50
The approximate value of the car 5 years from date of purchase is 11,092.50
