What is the difference between direct variation and direct proportion?
im not say that defferent.my question is inverse variation as a proportion.pls answerbecause i dont know the answer
How do you know that a direct variation is linear?
If the functional relationship is of the form y = cx where c is the constant of variation. In graphical form, it is a straight line through the origin.
When solving a problem listing every equation you know is usually the best way to find the correct one to use?
false
How do you know is an equation is linear?
You know if an equation is linear if it is a straight line. You can also know if the equation is y = mx + b where there are no absolute values nor exponents.
How do you know if an equation is equivalent?
An equation is equivalent to another equation, if they have the same solution.
How do you know if an equation is direct variation?
There are three ways: a table, a graph, and an equation.
How do you know if the equation is a direct variation?
When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. y=2x is direct variation y=x+2 is not direct variation
How do you know if x and y are direct variation?
Without the rest of the equation it is not possible to tell. * * * * * If the equation is in the form y = k*x where k is a non-zero constant, then it is.
What happen if you don't know direct variation?
For a start, you could get seriously ripped off every time you go shopping.
Can you have a negative coefficient in a direct variation?
Yes, you can have a negative coefficient in a direct variation. So if you had y = -7x, that would be a direct variation. If you have y = -x, I do not know, if that is what you mean. Hope it helped.

What are the 2 kinds of variation?
well there are surely two types of variations... anyone by chance happens to know the third kind, please let me know two types of variations- 1] direct variation 2] inverse variation
How do you know that a direct variation is linear?
If the functional relationship is of the form y = cx where c is the constant of variation. In graphical form, it is a straight line through the origin.

What is 0.15 repeating as a fraction and why?
If you want to know "why", you need to know how to solve it. Write: (Equation 1) x = 0.151515... Multiply that by 100 (the factor 100, a one followed by two zeros, is chosen because the repetition occurs every two digits): (Equation 2) 100 x = 15.151515... Subtract equation 1 from equation 2, and solve the resulting equation for "x". That will give you the number as a fraction.
