Answer:

Step-by-step explanation:
Total number of questions = 20
Possible options for each question = 4
Sample space contains the total number of possible outcomes.
For every question there are 4 possible ways to select an answer. This holds true for all 20 questions. Selecting an answer for a question is independent of other questions/answers,
According to the counting principle, the total number of possible outcomes will be the product of the number of possible outcomes of individual events. Possible outcomes for each of the 20 questions is 4. This means we have to multiply 4 twenty times to find the total number of possible outcomes.
So, the number of elements in the sample space would be:

Answer:

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Step-by-step explanation:
Let the number be x.

Dividing both sides by 4,

Subtracting 8 from both sides,

The number is -7.
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
For this case we have the following system of equations:

To solve, we add both equations:

We find the value of "x":

The solution is (-4,10)

Option C
Your original equation has no y-variable. It results in x = -2/3 when you solve for x which is a vertical line. Thus, if you want a line parallel to this that goes through point (- 1, - 4), you just set x equal to the x-value in that ordered pair.
Your parallel line is x = - 1.
Answer:
In summary, a line segment is a part of a line with two distinct end points. You can find the length of a line segment by solving an equation when the length of two lines segments is known. The length of line segments on the Cartesian plane can be found by counting the units that the line segment covers.
Step-by-step explanation:
Measure line segments. While the length or the measure is simply written AB. The length could either be determined in Metric units (e.g. millimeters, centimeters or meters) or Customary units (e.g. inches or foot). Two lines could have the same measure but still not be identical.
