Mathematics Determine whether the lines will be perpendicular when graphed.

For two lines to be perpendicular, the slope of one line must be the negative reciprocal of the slope of the other line. The slope can be determined by transforming the equation to its standard form of y = mx + b, where m = slope. Thus,

2y = 6 2y = 3x - 6 3/2x - 3, where m = 3/2

For the other line to be perpendicular, the slope of the equation for 2x + 3y = 6 MUST be m = -2/3. To check this, the equation can be transformed to its standard form:

3y...

The number of seats in the non-smoking section is 73 more than twice the number of seats in the smoking section. How many seats are in each section?
Let x = non-smoking seats, and y = smoking seats, with the total of x + y = 205.

From the conditions listed above, x = 2y + 73. Substituting for x in the original equation, we get 205 = 2y + 73…

When the different levels of functionality were compared highly functioning individuals took 55% of the academic courses the difference between the groups was significant (p< .01). Moderate functioning individuals took 46% of their classes as academic classes and for low-functioning persons only 40% of their classes were academic. When consideration was given to the setting in which the courses was taken it was found that 92% of the sample took

Note the distinct similarities. An examination of Escher's Circle Limit III can thus tell us much about distance in hyperbolic geometry. In both Escher's woodcut and the Poincare disk, the images showcased appear smaller as one's eye moves toward the edge of the circle. However, this is an illusion created by our traditional, Euclidean perceptions. Because of the way that distance is measured in a hyperbolic space, all of the
