Answer:
18-6y
Step-by-step explanation:
On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles per hour from his rate on his return trip. Alfonso found that in the same amount of time he could cycle 57 miles with the wind, he could go only 33 miles against the wind.What is his normal bicycling speed with no wind?
Answer:
between x=-1.5 and x = 0
between x = 0 and x = 1.5
Step-by-step explanation:
For the interval -1.5 < x < 1.5, we can see that the slope is negative (i.e from top left to bottom right). Hence it can be said that the graph is decreasing during this interval.
For the other parts of the graph (as shown) the slope is positive (i.e from bottom left to top right). in those areas, the graph is increasing.

Answer:
Step-by-step explanation:
From the given right angle triangle,
The hypotenuse of the right angle triangle is x
With m∠54 as the reference angle,
The unknown is the adjacent side of the right angle triangle.
The opposite side of the right angle triangle is 19
To determine x, we would apply the Sine trigonometric ratio.
Sine θ = opposite side/hypotenuse. Therefore,
Sin 54 = 19/x
x = 19/Sin54 = 19/0.809
x = 23.5 to the nearest tenth.
