Answer:
See below.
Step-by-step explanation:
2(x-2) = 3x+3(2x+1)
2x - 4 = 3x + 6x + 3
2x - 3x - 6x = 3 + 4
-7x = 7
x = -1
Answer: 30 feet per second
========================================
x = diameter, y = speed of water
y varies inversely with respect to x, so, y = k/x for some constant k
If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6
So the equation y = k/x turns into y = 3/x
Now plug in the diameter x = 0.1 to find the speed to be...
y = 3/x
y = 3/0.1
y = 30 feet per second
Answer: yes
Step-by-step explanation: slope is 4/3 and y intercept is 8
m= Y-20/0-9
4/3= y-20/-9
4/3 x -9 = y-20
-12 = y-20
Y=20-12
Y=8
8 would be the constant but in this situation there is a variable next to it so I’m not sure if it would be considered a constant
