Answer:
Distance from the point to the line will be ![\sqrt{5}m](https://tex.z-dn.net/?f=%5Csqrt%7B5%7Dm)
Step-by-step explanation:
We have given the equation of the line is y = 2x\
So the equation of line will be y-2x = 0
Point from which we have to find the distance is (-2,1)
Distance from a point to line is given by
, here A = -2 , B = 1 and C = 0
And point x = -2 and y = 1
So ![d=\frac{-2\times -2+1\times 1+0}{\sqrt{(-2)^2+1^2}}=\sqrt{5}m](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B-2%5Ctimes%20-2%2B1%5Ctimes%201%2B0%7D%7B%5Csqrt%7B%28-2%29%5E2%2B1%5E2%7D%7D%3D%5Csqrt%7B5%7Dm)
So distance from the point to the line will be ![\sqrt{5}m](https://tex.z-dn.net/?f=%5Csqrt%7B5%7Dm)
Answer:
Step-by-step explanation:
If we assume that initially
Number of red counter is 1
Number of blue counter is 3
Now to make ratio reverse you need to add 8 more red counters so that ratio becomes
9:3=3:1

Answer:
x = -0.5
Step-by-step explanation:
From your last step:
6.8x + 9.3 = -2.6 - 17x
We have two terms with x in them on different sides of the equation, so we want to bring the 'x terms' over to the same side.
Add 17x to both sides of the equation.
6.8x + 17x + 9.3 = -2.6
Collect like terms
23.8x + 9.3 = -2.6
Subtract 9.3 from both sides
23.8x = -2.6 - 9.3
23.8x = -11.9
Divide both sides by 23.8
x = -0.5
