Answer:
16) 6%
17) 4 years
18) 2 years
Step-by-step explanation:
The formula for these questions is I = PRT
16) 27 = 900 (R) (0.5)
Notice how I used 0.5 instead of 6 for the T. T has to be measured in years, not months and 6 months is half a year.
R = 0.06 = 6 %
17) 480 = 2000 (0.06) (T)
T = 4 years
18) 1080 = 4500 (0.12) (T)
T = 2 years
Answer:
slope = -1
Step-by-step explanation:
First, you need to know the slope formula: <u>y2 - y1</u>
x2 - x1
Now recognize the first point (-2,3) as (x1,y1) and the second point (2,-1) as (x2,y2)
Now that you have done that, plug in the numbers into the slope equation.
Which should look like this: <u>-1 - 3</u>
2 - -2
Now that your equation looks like this, recognize the denominator, we should know that a negative plus a negative equals a positive. So instead of subtracting the denominator of the equation, we are going to add the two numbers together, because x1 is negative. Now solve, you should get the answer -1.
<u>-1 - 3</u> <u>-4</u> = -1
2 + 2 4
