No, no value for x will result in you getting the same amount of money
I.e. on the first day if x =2 you earn 33. on the second day you would've earned 44. Of course this may be wrong so best to double check
I believe just 1 because an equilateral triangle can only be reflected on one line for the halves to be the same
36:39 in simplest form is 12:13
The answer is c. y=4x + 3
