Answer:

Step-by-step explanation:

The slope is the change in y divided by the change in x

If (x₁, y₁) and (x₂, y₂) are points on the line

slope m = (y₂ - y₁) / (x₂ - x₁)

m = (y₁ - y₂) / (x₁ - x₂)

Find the area of the figure.

Vesnalui [34]

Answer:

AREA = 4,850

Step-by-step explanation:

split into two pieces

formula for triangles- base x height divided by 2

20 x 50 = 100 / 2 = 50

(130 - 50 = 80)

80 x 120 = 9,600 / 2 = 4,800

add...

4,800 + 50 = 4,850

Answer:

$x^2 - 2x + 10$ , option B

Step-by-step explanation:

Complex numbers:

The most important relation that involves complex numbers is given by:

$i^2 = -1$

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

In this question:

The solutions are:

$x_1 = 1 - 3i, x_2 = 1 + 3i$

We have to find the polynomial. All option have $a = 1$ . So

$(x - (1 - 3i))(x - (1 + 3i)) = x^2 - x(1 + 3i) - x(1 - 3i) + (1 - 3i)(1 + 3i) = x^2 - x -3ix - x + 3ix + 1^2 - (3i^2) = x^2 - 2x + 1 - 9i^2 = x^2 - 2x + 1 - 9(-1) = x^2 - 2x + 10$

The correct answer is given by option b.
