Riddle battle. Tell me a riddle or no brainliest for you. Here is mine

What question can you never answer yes to?
Are you asleep yet?

right

Step-by-step explanation:

You should keep me as straight as can be, yet very few do. Most of the time I am slightly bent or curved. Your sadness usually causes me to bend further, but don’t bend me for too long or I may never be able to fully straighten out again. What am I?

Step-by-step explanation:

The answer to you riddle is: Are you asleep yet?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
