Mathematics

Mashutka [201]3 years ago

<u>Answer</u>

x = -4 plus or minus "i" times the square root of 6


<u>Explanation</u>

 −2x² − 16x − 44 = 0.

 −2x² − 16x = 44

Dividing by -2

x² + 8x = -22

x² + 8x + 4² = -22 + 4²

(x + 4)² = -22 + 16

(x + 4) ² = -6

(x + 4) = √-6

Remember √(-1) = i

(x + 4) = i√6                    or  (x + 4) = -i√6

x = -4 + i√6                          x = -4 - i√6

What do the following two equations represent? y=-3x+1 y+5= -3(x-2) a) the same line b) distance parallel lines c) perpendicular
Softa [21]

Answer:

  a) the same line

Step-by-step explanation:

The first equation is the "slope-intercept form" of the equation of a line with slope -3 and y-intercept +1. The second equation is the "point-slope form" of the equation of <em>the same line</em>. The "point" in this form is (x, y) = (2, -5), which is a point that satisfies the first equation:

   y = -3x +1

  -5 = -3(2) +1  .  .  .  . true

The two equations represent the same line.
