Answer:

It's B.

Step-by-step explanation:

We need to see if AB is perpendicular to BC. If it is then the product of the slopes of BC and AB  will equal -1.

A is the point (-5,5), B is (-3,2) and C is (-6, 0).

Slope of AB = (5 - 2) / (-5 - -3) =  3 / -2 = -3/2.

Slope of BC = (2-0) / (-3 - (-6) = 2 / 3.

The product of their slopes  is -3/2 * 2/3 = -1.

Therefore triangle ABC is right-angled.

Da<br> A<br> Solve the equation 2x^2+3=0
Anika [276]

Answer:

x = ±i(√6 / 2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Solving quadratics

<u>Algebra II</u>

Imaginary root i

  • √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2x² + 3 = 0

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

  1. [Subtraction Property of Equality] Subtract 3 on both sides:                        2x² = -3
  2. [Division Property of Equality] Divide 2 on both sides:                                  x² = -3/2
  3. [Equality Property] Square root both sides:                                                    x = ±√(-3/2)
  4. Simplify:                                                                                                             x = ±i(√6 / 2)
