Answer:

Undefined Slope

Step-by-step explanation:

If we look at the points given, then we can see that the X coordinates are the same. Putting this into (y2-y1)/(x2-x1), we can see that the denominator would be 0, meaning the slope would be undefined.

Answer:

undefined

Step-by-step explanation:

1) y₂-y₁/x₂-x₁

2)-22 -(-2)/ -4 -(-4)

3) -20/0

4) slope is undefined so there is only one line (same x coordinate)

Vitek1552 [10]

4/10 is also equal to 2/5 and 2+2 equals four therefore you would get 4/5 as your final answer

$\longrightarrow (-\dfrac{1}{2} +2)$

$\longrightarrow (-\dfrac{1}{2} +\dfrac{4}{2} )$

$\longrightarrow \dfrac{-1+4}{2}$

$\longrightarrow \dfrac{3}{2}$

$\sf \bold{\longrightarrow 1\dfrac{1}{2}}$ (final answer)

$\longrightarrow \sf 4(\dfrac{1}{2} +\dfrac{5}{4} ) + (-5)$

$\longrightarrow \sf 4(\dfrac{2}{4} +\dfrac{5}{4} ) + (-5)$

$\longrightarrow \sf 4(\dfrac{7}{4} ) + (-5)$

$\longrightarrow \sf 7-5$

$\longrightarrow \bold{\sf 2}$ (final answer)

Answer:

Therefore the value of x is

$x=1\pm\sqrt{19}i$

Step-by-step explanation:

Given:

$x^{2}+20=2x$ which is

$x^{2}-2x+20=0$

To Find:

x = ? using Quadratic Formula

Solution:

For a Quadratic Equation ax² + bx + c = 0 , Formula Method is given as

$x=\dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

On Comparing with above we get

$a=1\\b=-2\\c=20$

Substituting a , b , c in Formula method we get

$x=\dfrac{-(-2)\pm\sqrt{(-2)^{2}-4(1)(20)}}{2\times 1}\\\\x=\dfrac{2\pm\sqrt{-76}}{2}\\\\x=\dfrac{2\pm2\sqrt{19}i}{2}\\Dividing\ by\ 2\ we\ get\\\\x=1 \pm\sqrt{19}i$

Therefore the value of x is

$x=1\pm\sqrt{19}i$
