Since they are supplementary, both angles add to 180

m∠1+m∠2=180

Plug the values in

(3x-17)+(5x+21)=180

Add like terms

8x+4=180

8x=176

x=22

Hope this helped :)

Deffense [45]

Answer:

[0, 14] or 0 ≤ x ≤ 14

Step-by-step explanation:

The function would be:

y = 0.25x, where y-volume of water in the bucket after x minutes

The domain is x and the range is y

The bucket will be full after 3.5/0.25 = 14 minutes

The set of possible values of x is:

[0, 14] or 0 ≤ x ≤ 14
