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).
How do you know if 2 lines are parallel?
BEcause no matter how far they spread or how long you draw them, as long as they continue straight, they will never touch.
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'.
Explain why two lines of latitude never touch?
Lines of latitude are parallel to each other and never intersect because they are equidistant from the equator. As they run east-west around the globe, they maintain a consistent distance from each other, ensuring that they never touch or cross paths. This unique characteristic makes lines of latitude a useful reference point for determining locations on Earth's surface.
Can I make a quadrilateral with only one pair of parallel sides?
no? because in order to be a quadrilateral you need 4 sides. a pair of parallel lines in just 2 lines. parallel lines also never touch.
2 lines that will never intersect?
Parallel straight lines never intersect.
What are parellel line segments?
When 2 line segments are parallel to each other. If the lines did keep on going they would never touch each other
What are parelell lines?
Parallel lines are 2 long straight lines that don't touch each other
What is the two parallel lines?
2 parallel lines are lines that will never intersect
Why is it that two circles of latitude never touch?
Two circles of latitude never touch because latitude lines are parallel to each other and run horizontally around the Earth. They are all equidistant from each other and never intersect. The only exception is the Equator, which is the only latitude line that is also a great circle.
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
