Answer:
J p = 8t +12
Step-by-step explanation:
You can see that the p-values have differences of 8, while the t values have differences of 1. That means the "rate of change" is 8/1 = 8. This will be the coefficient of t in the equation you're looking for.
Only one answer choice has 8t as part of the equation:
p = 8t +12
______
<em>Additional comment</em>
If you decide to try the values of t in the offered choices, it often works to start with the second value of t. The answer choices are sometimes tailored to match for the first value in the table. Usually the second value of t will quickly identify the correct one.
For t=2, ...
F: p = 20·2 = 40 ≠ 28
G: p = 11·2 = 22 ≠ 28
H: p = 20·2 +12 = 52 ≠ 28
J: p = 8·2 +12 = 28 . . . . the correct choice
There was $135 in Roland's bank account after the two-month period.
Step-by-step explanation:
Step 1:
Roland out $180 in his account at the beginning of July. This reduced by 25% over the next two months.
We need to determine how much 25% of $180 is. To do so we convert 25% into a fraction and multiply with 180.
25% of $180 
So an amount of $45 reduced over two months.
Step 2:
To calculate the money Roland has in his account after two months, we subtract the amount reduced from the amount of money in his account at the beginning of July.
The amount of money in his bank account after the two-month period 
So there was $135 in Roland's bank account after the two-month period.
Answer:
65
Step-by-step explanation:
-3x^3 + 7x^2 -7x-1
Let x = -2
-3(-2)^3 +7(-2)^2 -7(-2) -1
According to PEMDAS, Powers first
-3(-8) +7(4) +14 -1
Then multiply
24 +28 +14-1
Then add and subtract
65
This is a reduction because the scale factor is in between 0 and 1.
