No. Direct variation describes a relationship between two variables. It has nothing to do with the value of a single number.
No, it does not.
No, y+2=x does not show direct variation. In direction variation you need to be able to multiply y by something to get x. In the question y+2=x, you have to add 2 to y to get x, which is not multiplying.)
Yes. y = 1x is the same as y = x which is the simplest case of direct variation. If you consider the equation y = mx + b, then a direct variation will always have b = 0 (i.e. the graph goes through the origin). The value of m is called the "constant of variation", and the equation is usually written as y = kx.
To determine if ( xy^3 ) shows direct variation, we check if it can be expressed in the form ( y = kx ), where ( k ) is a constant. In the case of ( xy^3 ), it is more appropriate to analyze it as a function of ( y ): if we isolate ( y ), we find ( y^3 = \frac{k}{x} ), indicating that ( y ) varies inversely with ( x ). Therefore, ( xy^3 ) does not show direct variation.
To represent one and three-fourths as a diagram, you can use a number line or a pie chart. On a number line, mark the whole number 1 and then divide the section between 1 and 2 into four equal parts, shading in three of them to show three-fourths. Alternatively, in a pie chart, you can draw a circle divided into four equal slices, shading three slices to visually depict one and three-fourths.
1 = 4/4 - 3/4 = 1/4
There is 18 hours in three fourths of a day.(24 ÷ 4) × 3 = 18 hoursNote, a day is accepted as being 24 hours.1 day = 24 hoursso 3/4 day = 3/4*24 or 18 hours
The scale of a map is decreased to show the representation of actual miles to the distance found on a map. If three fourths of an inch on a map was equal to 750 miles, an inch on the maps scale would equal 1,000 miles.

Ellipsis (...) is often used to show that text has been omitted from a direct quote. Square brackets ([ ]) can also be used to indicate that words have been deleted from a direct quote. An em dash (—) can sometimes be used to show omitted text in a direct quote.
