Are linear relationships sometimes, always, or never examples of directly proportional relationships

Mathematics

<span>Sometimes

Example:
As the number of DVDs you buy increases the total cost is added by 12$

For example,
1 DVD - 12$
2 DVD - 24$
3 DVD - 36$
...
100 DVD - 1200$

Hence, the relationship is proportionate.
It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)

Compute the permutation.
Anon25 [30]
So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula ^{a} P_{c} where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = ^{8} P_{3}
                                                                                       = 336

                                                <span> O R

</span>By using the formula Permutation =  \frac{a ! }{( a - c) !} where a is the number of available digits and c is the number of digits to be selected.<span>

</span>⇒  Permutation = \frac{8 ! }{( 8 - 3) !}
<span>
</span>⇒  Permutation = \frac{40, 320 }{120}
<span>
</span>⇒ Permutation = 336<span>

1) Explain to someone how you would do the problem -12 + 5. Explain to them how they would know if the final answer was going to
nadezda [96]

Answer:

1) -12 + 5 = -7 you just set it up and solve it like a regular problem and then to see if its a - or + we see what number was bigger so -12 is bigger then +5 so our answer is -7

2) 7 -3 + 15 - 2 - 3 + 6 so lets add up all the negative numbers and all the positive numbers so now we have + 28 - 8 so the we solve +28 - 8 = +20 again the sign goes with the bigger number!

Hope this helps!!! Good luck!!! ;)
