What grade are you in I can try to help but this looks difficult can you try to explain it for me
Simple interest means the interest at the end of each year will always be 8% of 2000 (assuming he doesnt pay some of it off), and will not be compounded with the existing interest.
To get a percentage, multiply by the percentage/100, in this case i.e. multiply by 0.08.
2000*0.08 = $160.
Therefore he has $160 of interest each year to pay.
Now we just need to work out how many lots of 160 go into 640, i.e. divide through.
640/160 = 4 - therefore he has had the loan for 4 years.
The answer is: B. Even function.
The explanation for this exercise is shown below:
1. You must substitute 
with 
in the function:
2. As you can see, 
, therefore it is an Even function.
A. is 15 and 25 and B. is 20 and 45
Answer: 88 degrees; acute triangle
Step-by-step explanation:
All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).
