Find thy slope of the line passing through the given point (2,0),(-6,8)

astraxan [27]

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (- 6, 8)

m = $\frac{8-0}{-6-2}$ = $\frac{8}{-8}$ = - 1

$\bf 0.2121\overline{21}\qquad \qquad \qquad x=0.2121\overline{21}\\\\ -------------------------------\\\\ \stackrel{\textit{moving the 21 to the left}}{\stackrel{100\cdot x}{100\cdot 0.2121\overline{21}}}\implies 21.2121\overline{21}\implies \begin{array}{llll} 21&+&0.2121\overline{21}\\ 21&+&x \end{array} \\\\\\ therefore\qquad \qquad 100x = 21+x\implies 99x=21 \\\\\\ x=\cfrac{21}{99}\implies x=\stackrel{simplified}{\cfrac{7}{33}}$

How many units long is a line segment whose endpoints have coordinates (-3,7) and (2,-5)?

Ilia_Sergeevich [38]

Answer:

D = 13 units

Step-by-step explanation:

Using Distance Formula to find the length.

Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

D = $\sqrt{(2+3)^2+(-5-7)^2}$

D = $\sqrt{(5)^2+(-12)^2}$

D = $\sqrt{25+144}$

D = $\sqrt{169}$

D = 13 units

How do you find the complex and real roots for x^4-3x^2+2=0

pogonyaev

X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0

so either x^2 - 2 = 0 or x^2 - 1 = 0

so x^2 = 2 or x^2 = 1

so x = sqrt 2 , - sqrt2, 1 , -1 Answer

all the roots are real
