Answer:
Step-by-step explanation:
-3x + 4y = 12
12(1/4x - 1/3y = 1)
-3x + 4y = 12
3x - 4y = 12
there is no solution
Answer: 22 minutes
Step-by-step explanation: 500-170 means that he drained 330 gallons of water so 330 divided by 15 gallons a minute so you get 22 so it takes 22 minutes to have 170 gallons left in the pool
Tan 25.5 = h/x
Tan 20.5 = h / x+1
x tan 25.5 = (x+1) tan 20.5
x 0.476975532 = (x+1) 0.373884679
0.476975532x = 0.373884679x + 0.373884679
Deduct both sides by .373884679
0.103090853x = 0.373884679
x = 3.6267 is the first person.
Add one to get for the second person
X = 4.6267

Step-by-step explanation:
Answer:
B yes, because every x value corresponds to exactly one y value
Step-by-step explanation:
A function means that each input goes to a different output
Each input goes to only 1 y value
