Solve x2 - 8x = 3 by completing the square. Which is the solution set

Simora [160]

Answer:

4\pm\sqrt{19}

Step-by-step explanation:

Move everything to left side

$x^{2} -8x -3 =0$

Now to solve this square equation we need to find Descriminant

$D=b^{2} -4ac=64+12=76$

As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula

$x_{1,2}=\frac{-b\pm\sqrt{D}}{2a} =\frac{8\pm2\sqrt{19}}{2}=4\pm\sqrt{19}$

Given a system of linear equations; explain your strategy for solving the system, show the math required to solve the problem, a

Alex73 [517]

Answer:

(2,3)

Step-by-step explanation:

The given system is

y=3x-3

y=2x-1

We equate both equations and solve for x.

$3x - 3 = 2x - 1$

Group like terms to get:

$3x - 2x = - 1 + 3$

$x = 2$

We put x=2 into y=3x-3 to get:

$y = 3 \times 2 - 3 = 6 - 3 = 3$

As an ordered pair the solution is (2,3)

Point A is located at (-2, 2). Point B is located at (-2, 0). What is the distance between point A and point B ?

Andrew [12]

Answer:

Step-by-step explanation:

Both point a and b have an x value of -2 so to find the distance between the two points we simply have to find the horizontal distance. We can do this by subtract the y value of the first point by the y value of the second point.

Point A y value : 2

Point B y value : 0

Distance between Point A and Point B : 2 - 0 = 2 units
