R = 8.5%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation
r = (1/2)((20475/17500) - 1) = 0.085
r = 0.085
converting r decimal to a percentage
R = 0.085 * 100 = 8.5%/year
The interest rate required to get
a total amount, principal plus interest, of $ 20,475.00
from simple interest on a principal of $ 17,500.00
over 2 years is 8.5% per year.

-x + 2y = 4
2y = x + 4
y = 1/2x + 2.....slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2
(-2,1)...x = -2 and y = 1
now we sub and solve for b, the y int
1 = -2(-2) + b
1 = 4 + b
1 - 4 = b
-3 = b
so ur perpendicular line is : y = -2x - 3
Answer: 2nd one
Step-by-step explanation: Look at the options. In all of the options, the number of 0's is 3 so you don't have to look for the zero's. Next look at the one's. The first 2 have 2 ones and the next 2 have 3. The number of ones in the data is 2 so you can eliminate the last 2. Then look at the 2's between the top 2. In the first one, there is 2 and in the second one there is only one. In the data table, there is one 2 so the answer has to be the 2nd one. Hope this helps :)
