The Temperature t is at least 75f

Explanation: Since t is at least 75 degrees Fahrenheit, this is the same as saying "t = 75 or more". In other words, t = 75 is the lowest we can go. We can consider it a floor value. So that's why we would write that t is greater than or equal to 75.

c. the third graph

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|
