What happens when the line y x is changed to y x 2?
If you mean: y = x and y = x+2 then the lines are then parallel to each
Why can't the sine of the theta equal 2?
because the ratio of one side of a triangle to the hypotenuse can never be more that one.
What is the intersection of these two lines 2x plus 4 equals y and x - y equals 2?
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
What are the points of intersection of the lines y equals x4 - 2 and y equals x2?
To find points of intersection of any functions, set them equal to each other: x4-2 = x2 x4-x2-2 = 0 factoring this yields: (x2-2)(x2+1)=0 by the zero identity, each of these factors can be set to zero to yield valid solutions: x2-2 = 0 x2 = 2 x = +/- sqrt(2) the second factor, when set equal to zero, yields an imaginary-valued solution. On a normal Cartesian coordinate plane, this means nothing. I assume you are only looking for points of intersection on a normal, real-valued Cartesian coordinate system (the normal x-y coordinate plane used in most elementary math classes). So, these two functions intersect at x = -sqrt(2) and x = sqrt(2)
How do you know when an equation has only one solution?
when the variable is to the power one you will only have one answer....2 solutions when to the power 23 when cubed etc.note: when multiple answers it is possible for answers to repeat ex. x^2+4x+4 =0would factor to (x+2)(x+2)=0 so x=-2 and x=-2 there is only one answer but it repeats. [Note: the graph of this parabola will 'just touch' the x-axis at x = -2]Also, it may seem that there is only one solution, for example x³ - 5x² + 8x - 6 = 0 looks like it only has one solution at x = 3 (as the graph of it will only cross the x-axis once at x = 3), but there are two more solutions which require the use of complex numbers, in this case namely x = 1 + i, and x = 1 - i (where i = √-1).
What shape has 2 sides?
There is not a shape that has 2 sides as these lines would never touch and thus would never become a closed fiqure or 'shape'.
What is the two parallel lines?
2 parallel lines are lines that will never intersect
What do parallel universes look like?
lines that never end and are straight and have 2 arrows at the endParallel is 2 lines that can go on forever and never intersectEx:__________________________________
Real world examples of skew lines?
given a room with 4 walls Line 1: The line that is the intersection of the floor and the west wall Line 2: The line that is the intersection of the ceiling and the north wall Lines 1 & 2 are skew. they never touch yet they are not in the same plane.
Does a triangle have 2 sets of parallel lines?
never
How are intersecting lines alike to perpendicular lines?
intersecting lines are alike because perpendicular lines have to intersect to be perpendicular. 2: They are the same because they touch another line so they are the same.
What are 2 lines in the same plane that never intersect?
Two lines that are in the same plane and never intersect are called "Parallel," meaning that they are lines with the same slope, but not y-intersect.
Does apple repair iPod Touch screens free?
no never have never will but it only costs $2
How many parallel lines does a triangle have?
It has no paralel lines. A paralel line are two lines that never cross. If you notice, in a trinagle all lines are touching all other lines.
What are perpedicular lines?
Perpendicular Lines are two or more lines that will intersect (come together) at some point along their paths. Paralell lines are 2 or more lines that will never intersect at any point in their paths.
Are 2 lines in intersecting planes always sometimes or never skew?
sometimes skew
What is a parallel thing?
2 things running beside each other, that will never cross no matter which way you go. For example,the top and bottom lines of a square. These 2 lines can extend infinitely in either direction and never intersect, therefore, they are parallel.
