Answer:
{3,6,9,0}
Step-by-step explanation:
The range is the set of all second elements of ordered pairs (y-coordinates).
Answer:
21 minutes divided by 7 walls = 3 minutes per wall for 5 people.
Assuming each worker has the same exact productivity, one person would take 15 minutes to paint a single wall (3 minutes x 5 people to get the amount of time for 1 worker per wall).
15 minutes for one worker multiplied by 5 walls = 75 minutes for one worker. Divide 75 minutes by 3 people = 25 minutes to paint all 5 walls with 3 people.
Step-by-step explanation:
M= 5x B= -6
M= -1/2 B= 5
M= 5x B= 2y
M= x B= y
Answer:
x=43 and y=22
Step-by-step explanation:
x + y = 65
let y = smaller the y = x -21
Then x + (x - 21) = 65
2x = 86
x = 43
then plug that into y = 43 - 21 = 22
