Equation required for this question:
an • 1.072^n = 14,580
Where a = payment every half year and n = number of half years
There are 12 half years in 6 years.
Therefore n = 12, substitute this.
12a • 1.072^12 = 14,580
12a = 14,580 / 1.072^12
12a = 6,330~
a = 527.5 ~
Question 1:
The answer is A: Sam.
His table is the only one that follows the conditions set in the question.
Question 2:
Choosing two points; (0, 14) and (4, 10)
Slope (m) =

= -1
Thus, equation,


I'm getting that for my equation of the line, so my best guess is that the answer is C.
The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.
The answer is C. ( I believe )
Answer:
The slope of the line is m = 3
Step-by-step explanation:
You can easily verify that if x decreases by 2 (e. g., from -4 to -2), y increases by 6. Thus, the slope is m = rise/run = 6/2 = 3
Step-by-step explanation:
5(-3) + 2 = (-15) + 2 = -13.
-4(-3) + 5 = 12 + 5 = 17.
Since -13 ≠ 17, x = -3 is not a solution.
