Answer: B and D
Step-by-step explanation:
B=-2
D=2
The negative and positive signs cancel out, leaving you with zero.
Ex: you take two steps back, but then you take two steps forward so you're back where you started (0).
The sequence is geometric and the common ratio is 2
Answer:

Step-by-step explanation:
The formula for the total accrued amount is
A = P(1 + rt)
Data:
P = $500
r = 6.5 % = 0.065
t = 30 mo
Calculations:
(a) Convert months to years
t = 30 mo × (1 yr/12 mo) = 2.5 yr
(b) Calculate the accrued amount
A = 500(1 + 0.065 × 2.5)
= 500(1 + 0.1625)
= 500 × 1.1625
= 581.25

(c) Calculate the accumulated interest

All you have to is solve for Y.
Solve the exponent first
5^2 = 5 x 5 = 25
Then multiply 10 by 25
10 x 25 = 250
250 is your answer
Answer:
B(x) is the better option
Step-by-step explanation:
Let's say that these functions represent the pay f(x) in hours, x. Function B would increase linearly on a greater scale because each X is being multiplied by 20.
You'll notice this trend for larger numbers, such as 10.
A(x) = 5(10) + 20 = 70
B(x) = 20(10) + 5 = 205
Therefore, your answer is B.
