Answer:
\/
Step-by-step explanation:
Inverse of 1.5x+4: 2(x-4) /3
Slope of 1.5x+4: m=1.5
So with this you will be using proportions, and this proportion is gonna be
Firstly, you want to cross-multiply to get
Next, just divide each side by 4, then your answer will be
Answer:
y = 4x^2 + 5 has the narrowest graph.
Step-by-step explanation:
The larger the coefficient of x^2 is, the narrower the graph will be. Thus:
y = 4x^2 + 5 has the narrowest graph.
Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.
X = -2(5 + (sqrt34)) OR 2((sqrt34) - 5)
