Answer:
c. number shows the proportional relationship between x and y...
Answer:
(a) 6.2843 billion
(b) 6.8716 billion
Step-by-step explanation:
Since there is a constant growth rate of 1.5% per year, and the population in 2002 was 6.1 billion people. The general equation for the total world population, in billions, after 2002 is:

With t being the time, in years, after 2002.
a) What was the population in 2004?

b) What was the population in 2010?

The difference (d)
This is calculated as:

<h3>
Answer: 0.05x+10</h3>
Work Shown:
x = number of miles
Cost of company A = 0.09x+50.50
Cost of company B = 0.14x+60.50
Subtract the two expressions (B-A) to find the difference in price
B-A = (0.14x+60.50)-(0.09x+50.50)
B-A = 0.14x+60.50-0.09x-50.50
B-A = (0.14x-0.09x) + (60.50-50.50)
B-A = 0.05x+10
Answer:
0
Step-by-step explanation:
3x^2 + y ( If x = 1, and y = -3)
= 3(1)^2 + (-3)
= 3 + -3
= 0
