I have my notes here that will help you in answering the problem:
Test to determine if a function y=f(x) is even, odd or neither: Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even. If f(-x) = - f(x), the function<span>is odd.

I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
C: 8 weeks
Step-by-step explanation:
Using the information provided in the question we can create the following model for this scenario. We have the total amount needed, an initial starting point of money he had already saved and the amount he is able to save each week which is multiplied by the variable number of weeks (x) which we need to solve for...
565.95 = 205.00 + 46.00x ... subtract 205.00 from both sides
360.95 = 46.00x ... divide both sides by 46.00
7.84 = x
We can now see that it would take Sayir a total of 7.84 weeks to save that money but since he gets paid on a weekly basis we would need to round up to 8 weeks.
5x+4x+3x=180
12x=180
x=30
3(15) = 45 {angle J}
4(15) = 60 {angle H}
5(15) = 75 {angle G}
Double check that the sum of all angles is 180
45+60+75=180
180=180
