What is an arrow with two lines in mathematics?
== == It means 'implies'. So A --> B means 'if A is true then B is true' or 'A implies B'
How do you identify two linear equations that are parallel using slopes of two lines?
Two linear equations that are parallel with have the sameslope, or the m value in y = mx + b will be the same.For example, y = 3x + 5 is parallel to y = 3x - 6
What is 4a equals 4-b 4a equals 2-b?
They appear to be the equations of two parallel lines in the a-b plane.
What is the relationship between the equations of parallel lines?
They have the same slope. If you write the lines in the slope-intercept form, you will get, for each line: y = ax + b where a is the slope, and b is the y-intercept (where the line crosses the y-axis). For two or more parallel lines, the coefficient "a" will be the same.
How do you make 3 different parallelograms with area 18?
Select any number B. Draw two parallel lines that are B units apart. Calculate 18/B and mark out segments of length 18/B on the two lines. They can be anywhere along the entire [infinite] lengths of the lines, though obviously, it is easier to work with them if there are reasonably near each other. Join together the left ends of the two segments; join together the right ends. These parallelograms will have areas of 18 units. You can (1) select just one segment on one of the parallel lines and three on the other, or (2) select three pair of segments on the two parallel lines or (3) draw a fresh set of parallel lines for each parallelogram.
