Multiplication:-
If: f/3 = 0.27
Then by multiplying both sides by 3: f = 0.81

Since no points were given, for any point (x,y), plug the x and y values of the point into the equation. If you get a contradiction, ie 5=3 or something similar, then the point does not lie on the graph.
The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
The equation y = -2.5 represents a horizontal line on the Cartesian plane passing through the point (-2.5, 0). This line is parallel to the x-axis and has a slope of 0. The solution to this equation is all real numbers on the y-axis that have a value of -2.5.
The period is the length of x over which the equation repeats itself. In this case, y=sin x delivers y=0 at x=0 at a gradient of 1. y next equals 0 when x equals pi, but at this point the gradient is minus 1. y next equals 0 when x equals 2pi, and at this point the gradient is 1 again. Therefore the period of y=sinx is 2pi.
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
A linear equation is the equation of a line and that consists of an infnite number of points. What you have, in x = -4 and y = -1/3, is a single point. A single point is not a line and so there cannot be a linear equation (suitable for a line) to represent a point.
Put a parenthesis before the 2 and after the 4.4 (2 x 4.7 - 4.4) = 9.4 - 4.4 = 5 45 divided by 5 times 6 equals 54
Do you mean 0.4y+0.6y = 3y -36? If so then: y = 18
To check this, you substitute the values for x and y into the equation. At (1,2) x equals 1 and y equals 2 so substituting this in we get: x + 2y = 1 + 2(2) = 1 + 4 = 5 And since it equals 5 like in the original equation the point is represented by it.

The diagonal line collapses into a single point on that line.
It's the equation of a straight line. Every point on the line is a solution to the equation. There are an infinite number of them.
Point slope equation: Y=3X+12
it equals 1
It is a linear equation in two variables, x and y. Any point on the line defined by the equation will satisfy the equation and conversely, any ordered pair that satisfies the equation will represent a point, in the Cartesian plane, will be on the line.
