Can someone solve point-slope lines and show work? I’m confused
Bad White [126]

Answer:

Option (2)

Step-by-step explanation:

Equation of a line passing through a point (x', y') and slope 'm' is given by,

y - y' = m(x - x')

From the question in the picture attached,

Slope of the line 'm' = -\frac{7}{10}

Line passes through a point (80, -71).

Equation of the line will be,

y + 71 = -\frac{7}{10}(x-80)

y = -\frac{7}{10}x+56-71

y = -\frac{7}{10}x-15

Option (2) will be the answer.

 Solve by completing the square <br> x^2=11x-2
son4ous [18]

Answer: x = ± 11+√113   ;

                        ______

                              2

Step-by-step explanation:

x^2=11-2

Add two to both sides

x^2+2=11x-2+2

Simplify

x^2+2=11x

Subtract 11x from both sides

x^2+2-11x=11x-11x

Simplify

x^2-11x+2=0

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>a</em> = 12 cm

<em>c</em> = 17 cm

<u>Step 2: Solve for </u><em><u>b</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                            12² + b² = 17²
  2. Evaluate exponents:                                                                                         144 + b² = 289
  3. [Subtraction Property of Equality] Subtract 144 on both sides:                     b² = 145
  4. [Equality Property] Square root both sides:                                                      b = √145
  5. [√Radical] Evaluate:                                                                                         b = 12.0416
  6. Round:                                                                                                               b ≈ 12.0
