P has a y intercept of 6 and a slope of 1 up for every two to the right, 1/2
y = (1/2) x + 6
Q has a y intercept of -3 and a slope of 4 down from every one to the right, -4.
y = -4x - 3
For the solution we equate the two ys,
(1/2)x + 6 = -4x - 3
x + 12 = -8x - 6
9x = -18
x = -2
y = (1/2) (-2) + 6 = 5
Solution: (x,y)=(-2, 5)
Answer:
3*45=135 minutes.
Step-by-step explanation:
Hello there!
Start by seeing if there is an equal rate in the qmount of people that we are working with.
27/9=3 (so there's one)
3*45 (the amount of time when 9 people are in line)= 135 minutes
Have a great day!
