Answer:

\frac{20}{3}

Step-by-step explanation:

we have  : lines 2 x + 4 y = 0 and 2 x + y = 10

   Let ,

2 x + 4 y = 0............. (1)

2 x + y = 10...............(2)

solve these equations for x and y

Now subtract (2)  from (1) ,we get

3y=-10

⇒y = \frac{-10}{3}

Put the value of y in (1) , we get

2x+4(\frac{-10}{3}) = 0

⇒2x= \frac{40}{3}

⇒x=\frac{20}{3}

∴ Point  of intersection is (\frac{20}{3},\frac{-10}{3} ).

Hence,the x-coordinate of that point is \frac{20}{3}.

Find the distance between the points (1, 7) and (10, 1)<br> Please help:)
klio [65]

Answer:

<em>The distance between the points (1, 7) and (10, 1) is 10.82 units</em>

Step-by-step explanation:

<u>Distance between two points </u>

The distance between points A(x,y) B(w,z) can be calculated with the formula:

d=\sqrt{(z-y)^2+(w-x)^2}

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:

d=\sqrt{(1-7)^2+(10-1)^2}

d=\sqrt{(-6)^2+(9)^2}

d=\sqrt{36+81}=\sqrt{117}\approx 10.82

The distance between the points (1, 7) and (10, 1) is 10.82 units
