Answer:
(-2, 4)
Step-by-step explanation:
y = -3x - 2
y = -x +2
=> -3x - 2 = -x +2
-3x + x = 2 + 2
-2x = 4
x = -2
-x + 2 = y
2 + 2 = y
4 = y
You would take the amount of increase and divide it by the amount of total cost over the time period of certain months. Then you would multiply that number by the percentage of increase gained, and subtract 96.12 to get your answer.
The answer would be 15.24cm
Answer:
a25 = -134
Step-by-step explanation:
For first term a1 and common difference d, the formula for the n-th term is ...
an = a1 + d(n -1)
You want to evaluate this for n=25, a1=-14, d=-5. Filling in the numbers and doing the arithmetic, you get ...
a25 = -14 -5(25 -1) = -14 -120
a25 = -134
