At noon the temperature was 5*c. over the next 4 hours the temperature dropped another 7 degrees. then every hour until 9: 00 the temperature rose 3 degrees. what was the temperature at 9: 00?

5-7=-2

-2+(3 x 5)=13

13 is the answer

also the 5 came from the leftover time. because if it started at 12 and then 4 hours passed it would now be 4 and there are 5 hours left from 4 to 9

you need to show us the graph.

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
