Answer: click the third one :)
Step-by-step explanation:
Answer:
y=mx+b
y=2x+8
y=x+6
Step-by-step explanation:
y=2x+8 y=x+6
slope:2 slope:1
y-int:8 y-int:6
x. y x. y
0. 8 0. 6
1. 10 1. 7
First we define variables:
x = distance traveled by player A
y = distance traveled by player B
We have the following system of equations:
x + y = 1550
x = 9y
Solving the system we have:
x = 1395
y = 155
Answer:
x = 1395 yards (player A)
y = 155 yards (player B)
Answer:
72
Step-by-step explanation:
39/1.5 = 26 km per hour
51/3 = 17 km per hour
Then you need the mean. 26+17/2 = 21.5 km per hour
