Answer:

x = 10

Step-by-step explanation:

x(2+2)+5x-12=x(4+4)-2 \\ x(4) + 5x - 12 = x(8)  - 2 \\ 4x + 5x - 12 = 8x - 2 \\ 9x - 12 = 8x - 2 \\ 9x - 8x = 12 - 2 \\ x = 10

On a coordinate plane, 2 lines are shown. Line P Q has points (negative 5, 3) and (5, 1). Line R S has points (negative 4, negat
Romashka-Z-Leto [24]

Given:

Line P Q has points (-5, 3) and (5, 1).

Line R S has points (-4, -2) and (0, -4).

To find:

The relationship between lines PQ and RS.

Solution:

If a line passing through two points, then the slope of line is

m=\dfrac{y_2-y_1}{x_2-x_1}

Line P Q has points (-5, 3) and (5, 1). So, slope of line PQ is

m_1=\dfrac{1-3}{5-(-5)}

m_1=\dfrac{-2}{5+5}

m_1=\dfrac{-2}{10}

m_1=\dfrac{-1}{5}

Line R S has points (-4, -2) and (0, -4). So, slope of line RS is

m_2=\dfrac{-4-(-2)}{0-(-4)}

m_2=\dfrac{-4+2}{0+4}

m_2=\dfrac{-2}{4}

m_2=\dfrac{-1}{2}

Slopes of two parallel lines are equal.

m_1\neq m_2

They are not parallel because their slopes are not equal.

Therefore, the correct option is C.
