Answer:
look at explanation for answer...
Step-by-step explanation:
y = 2x + 1
so you want the coordinates (1,3)
so you input the x coordinate into the equation,
y = 2(1) + 1
y = 2 + 1
y = 3
but if you have to write a new equation to get coordinates (1,3)
you could write the equation
y = 3x
Answer: 6
Step-by-step explanation: 12*3=36; square root 36 is 6.
X - speed of the current
40+x - speed with current
40-x - speed against current
t-time
(40+x)*t=100
(40-x)*t=60
40t+xt=100
<span> + 40t-xt = 60
</span> 80t =160
t = 2
40t+xt=100,
40*2+2x=100
80+2x=100
2x=100-80
2x=20
x=10 mi/h
10 mi/h speed of the current.
