What is the value of x so that the line segment with endpoints W(x, −2) and X(5, −4) is parallel to the line segment with endpoi

coldgirl [10]

Answer:

x equals six start fraction one over two end fraction

Step-by-step explanation:

Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.

Slope of YZ is:

$m = \frac{y_2-y_1}{x_2-x_1}=\frac{2-6}{2-5}=\frac{-4}{-3}=\frac{4}{3}$

Since they are parallel, then WX has a slope of 4/3 too.

Slope of WX is:

$m = \frac{y_2-y_1}{x_2-x_1}\\\\\frac{4}{3}=\frac{-2--4}{x-5}\\\\\frac{4}{3}=\frac{2}{x-5}\\\\\frac{4}{3} (x-5) = 2\\\\4x -20=6\\\\4x = 26\\\\x = 6\frac{1}{2}$

Consider the following graph of an absolute value function

Ahat [919]

The domain is -∞ < x < ∞

The range is -∞ < x ≤ 3

The graph is increasing from -∞ < y < 3

The graph is decreasing from 3 > y > -∞

The local maximum is at ( - 2, 3 )

There are no local minimums

A coat that usually costs $123 is marked off 1/3 (one-third) off. What is the sale price of the coat? Round to the nearest dolla

serg [7]

Basically you just divide:

123/3 = 41

So the sale price of the coat would be $41
