Which equation has the solutions X=1 +-SQRT 5?

Vesna [10]

Answer:

D is correct. $x^2-2x-4=0$

Step-by-step explanation:

We are given the root of the equation

$x=1+\pm \sqrt{5}$

If we are given solution of the equation then find equation using formula.

If a and b are the solution of equation then equation would be (x-a)(x-b)=0

Here, $a=1+\sqrt{5} , b=1-\sqrt{5}$

Equation form would be $(x-1-\sqrt{5})(x-1+\sqrt{5})=0$

Now we simplify the above equation to get correct option.

$x^2-x+x\sqrt{5}-x+1-\sqrt{5}-x\sqrt{5}+\sqrt{5}-5=0$

$x^2-2x-4=0$

So, D is correct. $x^2-2x-4=0$

a fitness center offers yoga for $10 per class and sells yoga mats for 19.95. A person paid a total cost f $139.95 to the fitnes

Ne4ueva [31]

10x + 19.95 = 139.95

Subtract 19.95 from both sides
10x =130.00
Divide both sides by 10

X = 13

Sphinxa [80]

Ur perpendicular line will have -1 as the slope

y - y1 = m(x - x1)
slope(m) = -1
(2,5)...x1 = 2 and y1 = 5
now sub
y - 5 = -1(x - 2) can be written like : y - 5 = -(x - 2)
