Graph the function y = |1.6x – 2| – 3.2. Over which interval is the function increasing?
klasskru [66]
You are to graph   <span>y = |1.6x – 2| – 3.2.  I trust you know that the graph of y=|x| is v-shaped, opening up, with vertex at (0,0).

Let's rewrite </span><span>y = |1.6x – 2| – 3.2 by factoring 1.6 out of  |1.6x - 2|:

                     </span><span>y = 1.6*|x – 2/1.6| – 3.2

This tells us that the vertex of   </span><span>y = |1.6x – 2| – 3.2   is at (2/1.6,  -3.2).  If you need an explanation of why this is, please ask.

Plot the vertex at (1.25, -3.2).
Find the y-intercept:  Let x = 0 in  </span><span>y = |1.6x – 2| – 3.2 and find y:

                                                      y = 2-3.2 = -1.2

The y-intercept is located at 0, -1.2)

Plot this y-intercept.

Now draw a straight line from the vertex to this y-intercept.  Reflect that line across the y-axis to obtain the other half of the graph.</span>

Given a line segment that contains the points A,B, &amp; C in order, if AB = x + 12, and BC = 2x - 4, and AC = 26, find x.
Troyanec [42]

Answer:

x = 6

Step-by-step explanation:

If A, B and C lies on a straight line in order, then;

AB+BC = AC

x+12+2x-4 = 26

x+2x+12-4 =26

3x+8 = 26

3x = 26-8

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

Hey guys could you help?

Answer:

Canadian railcars show weight figures in both imperial and metric. Canadian railways also maintain exclusive use of imperial measurements to describe train length and height in feet and train masses in short tons. Canadians typically use a mix of metric and imperial measurements in their daily lives.
