16% = 0.16
1/6 = 0.16666
1.6x10^6 = 1600000
0.166 = 0.166
order from greatest to least:
1.6x10^6, 1/6, 0.166, 16%

Answer:
y=x-2
Step-by-step explanation:
If you have drawn the graph of
.
To determine the equation of the line which should be drawn to solve the equation: x² - 4x +3=0
Simply carry out the subtraction: ![x^2 - 3x + 1 -(x^2 - 4x +3)](https://tex.z-dn.net/?f=x%5E2%20-%203x%20%2B%201%20-%28x%5E2%20-%204x%20%2B3%29)
![\implies x^2 -3x + 1-x^2 + 4x -3 \\= x^2 - x^2+ 4x - 3x-3 + 1\\=x-2](https://tex.z-dn.net/?f=%5Cimplies%20x%5E2%20-3x%20%2B%201-x%5E2%20%2B%204x%20-3%20%5C%5C%3D%20x%5E2%20-%20x%5E2%2B%204x%20-%203x-3%20%20%2B%201%5C%5C%3Dx-2)
The equation of the line which should be drawn is: y=x-2
What this means is simply:
If
![y = x^2 - 3x + 1$ and $y=x-2,$ then:\\x^2 - 3x + 1=x-2\\x^2 - 3x + 1-x+2=0\\x^2 - 4x + 3=0](https://tex.z-dn.net/?f=y%20%3D%20x%5E2%20-%203x%20%2B%201%24%20and%20%24y%3Dx-2%2C%24%20then%3A%5C%5Cx%5E2%20-%203x%20%2B%201%3Dx-2%5C%5Cx%5E2%20-%203x%20%2B%201-x%2B2%3D0%5C%5Cx%5E2%20-%204x%20%2B%203%3D0)
Answer:
x=1.75 hour
Step-by-step explanation:
200km=2.5
140km=x
2.5 * 140=200x
350=200x
x=350/200
x=1.75
the time it will take is x=1.75 hour
