Is the airplane’s altitude a function of time? yes, because any input of time results in only one output of altitude. yes, because the airplane increases and decreases in altitude at the same rate. no, because each output of altitude has more than one input of time. no, because the altitude is constant between 60 minutes and 130 minutes.

subtract 60 from 130 to get your answer for the altitude

this is false ^.^ lol

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
