Explain why: if x and y are odd integer numbers then x+y+3 is an odd internet number

Well not Internet numbers, but integers.

Firstly, adding integers makes integers.

Secondly, adding an odd number (x) to another odd number (y) makes an even number, and adding another odd number (3) to it makes it odd again.

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
