  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from table.</em>

Point (-1, -1)

Point (0, -5)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.  Rate of change and slope are identical.

  1. Substitute [SF]:                    m=\frac{-5+1}{0+1}
  2. Add:                                     m=\frac{-4}{1}
  3. Divide:                                 m=-4

What is the solution to ln (x2 - 16) = 0?
bogdanovich [222]
ANSWER

x = \pm \sqrt{17}
EXPLANATION

The given equation is

ln( {x}^{2} - 16) = 0

Take antilogarithm of both sides to base e.

{e}^{ ln( {x}^{2} - 16) } = {e}^{0}

This will simplify to

{x}^{2} - 16 = 1

Group like terms to obtain,

{x}^{2} = 1 + 16

{x}^{2} = 17

Take square root of both sides to get,

x = \pm \sqrt{17}

What is the solution to the system of equations? {2x-2y+z=5 2x-2y+3z=7 -3x-3y+3z=9
german
2x - 2y + z = 5....multiply by -1
2x - 2y + 3z = 7
-------------------
-2x + 2y - z = -5 (result of multiplying by -1)
2x - 2y + 3z = 7
-------------------add
2z = 2
z = 2/2 = 1

2x - 2y + z = 5.....multiply by 3
-3x - 3y + 3z = 9...multiply by 2
-------------------
6x - 6y + 3z = 15 (result of multiplying by 3)
-6x - 6y + 6z = 18 (result of multiplying by 2)
-------------------add
-12y + 9z = 33

-12y + 9(1) = 33
-12y + 9 = 33
-12y = 33 - 9
-12y = 24
y = -24/12
y = -2

2x - 2y + z = 5
2x - 2(-2) + 1 = 5
2x + 4 + 1 = 5
2x + 5 = 5
2x = 5 - 5
2x = 0
x = 0

solution is : (0,-2,1)
