step-by-step explanation: if the baby uses 15 diapers every 2 days, to get the answer we would need to determine the number of days then multiply that by 15. are 365 days in a year, divide that by 2 and you get 182.5 days. multiply that by 15 and it's 2737.5 but since a baby can't use a half diaper, we'll round it to 2738.
by "units left" i'm assuming you mean from observing the number on a standard number line.
in that case, the number 7 units to the left of -15 would be -22, as you're basically subtracting 7 from -15, which is -22.
f(x) -4 shifts it down 4 units from f(x)
when we add or subtract from f(x) this causes a shift in the vertical direction.
when we add it shifts it up.
when we subtract is shifts it down
f(x) -4 shifts it down 4 units
