(×-5) second power equals 3​
Snezhnost [94]

Answer: x_1=6.73\\\\x_2=3.26

Step-by-step explanation:  

Given the following expression:

(x-5)^2=3

And knowing that:

(a\±b)^2=a^2-2ab+b^2

We get:

x^2-2(x)(5)+5^2=3\\\\x^2-10x+25=3

Move the 3 to the left side of the equation:

x^2-10x+25-3=0\\\\x^2-10x+22=0

Apply the Quadratic formula:

x=\frac{-b\±\sqrt{b^2-4ac} }{2a}

In this case:

a=1\\b=-10\\c=22

Substituting values into the Quadratic formula, we get:

x=\frac{-(-10)\±\sqrt{(-10)^2-4(1)(22)} }{2(1)}\\\\\\x_1=6.73\\\\x_2=3.26

AB passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to AB ?
Aleksandr [31]

Answer:

3y + 5x = 0

Step-by-step explanation:

The slope of the line = (y2-y1) / (x2-x1) = (5-0)/(-6-(-3))

= 5 / -3 = -5/3

Using the point-slope form , the line that passes through the origin and parallel to this line is

y - 0 = -5/3(x - 0)

y = -5/3 x

Multiply through by 3:-

3y = -5x

5x + 3y = 0
