When two quantities, say X and Y, are related in such a way that an increase or decrease in the value of X results in an increase in the value of Y, direct variation occurs, whereas indirect or inverse variation occurs when an increase in the value of X results in a decrease in the value of Y and vice versa.
<h3>
Difference between direct variation and inverse variation:</h3>
- To give the reader a hint, direct variation equations use the same phrase.
- The phrase is either "directly proportional" or "directly varies."
- The area of a square, for example, varies directly from the square of its side.
- Direct variation occurs when two quantities, say X and Y, are related in such a way that an increase or decrease in the value of X results in an increase in the value of Y.
- Inverse variation is a relationship between two variables in which the value of one increases while the value of the other decreases.
- Indirect or inverse variation occurs when two quantities, say X and Y, are related in such a way that an increase in the value of X results in a decrease in the value of Y and vice versa.
Therefore, direct variation occurs when two quantities, say X and Y, are related in such a way that an increase or decrease in the value of X results in an increase in the value of Y whereas indirect or inverse variation occurs when two quantities, say X and Y, are related in such a way that an increase in the value of X results in a decrease in the value of Y and vice versa.

Answer:
supplementary angles add up to 180°
given y=65° thus...
x+y=180°
x + 65°=180°
x=180°- 65°
x=115°
Answer:
It's the last choice: (x + 5) / (x^2 - 7x + 10).
Step-by-step explanation:
x^2 - 7x + 10
= (x - 5)(x - 2)
If these are a denominator of a rational expression then 2 and 5 will be excluded values.
This is because x = 5 or x = 2 makes the denominator = zero and the function then becomes undefined.
So the answer is (x + 5) / (x^2 - 7x + 10).
Answer: 48hm
Step-by-step explanation:
48hm = 4800m
480m < 4800m
Answer:There are 23green marbles
Step-by-step explanation:
If Red marbles x
Green marbles 2x-5+x=37
Total is 3x-5=37
3x=37+5
X=14
Green therefore=2(14)-5=23
