Answer:
48
Step-by-step explanation:
The rule is every parent means 8 students.
6 * 8 is 48.
Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05
Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x
ANSWER
D) (a + 1, b + m)
EXPLANATION
The given line passes through (a,b) and has slope m.
The equation is:

When x=a+1, we obtain

This


Therefore,(a + 1, b + m) must also lie on this line.
The correct answer is D.
