Answer:
![y=\frac{-3}{4} x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-3%7D%7B4%7D%20x%2B2)
Step-by-step explanation:
First, we can find the slope using the slope equation and two of the points.
Slope equation:
![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
I'm going to use the first two points just so I can avoid the fraction... Substitute the x and y values into the equation.
![m=\frac{2-5}{0--4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2-5%7D%7B0--4%7D)
Simplify:
![m=\frac{-3}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3%7D%7B4%7D)
Now that we have the slope, all we need is the y-intercept. Luckily, it gives it to us in the table. The x value of y-intercepts will always be 0. Looking at the table, we see that the point where x=0 is (0,2). Thus, the y-intercept is 2. Your final equation is
![y=\frac{-3}{4} x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-3%7D%7B4%7D%20x%2B2)
Answer:
55.734 mph
Step-by-step explanation:
Let's call the wind speed x and the time of flight t.
Then, we can write the following equation, knowing that the distance is equal speed times time of flight:
910 = (350+x) * t
660 = (350-x) * t
If we isolate t in both equations and compare its value, we have that:
910 / (350+x) = 660 / (350-x)
(350+x)/(350-x) = 910/660
350 + x = 1.3788 * (350-x)
350 + x = 482.58 - 1.3788x
2.3788x = 132.58
x = 55.734 mph
Answer:
25.60 €.
Step-by-step explanation:
£3 is €4
So £1 is €4/3
and £19.29 = 19.20 * 4/3
= 25.60 €
