Use the domain and range of each of the following relations to determine which is a function. A. {3,7,-7,9}
B. { (3,9), (7,-4), (-7,7) }
C. { (3,9), (7,-4), (3,7) }
D. { (3,9), (7,-4), (7,6), (-7,7) }

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.

step-by-step explanation:

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

1.44 centimeters is the correct answer

the answer is no solution, glad i could .
