(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
If you mean: y=6+x/ x=7 Then that is the equation for a line. Put in any number for "x" and "y" will always be 6 more than that. In this case, y=13
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
(x^2 - y^2) / (x - y) Apply the difference of squares formula: (x + y)(x - y) / (x - y) Assuming x is not equal to y, we can cancel terms leaving x + y When x = y, the denominator becomes 0, and the equation gives no information.
The answer is 79. Since you know the values of x and y, you can simply substitute them into the equation to find the answer. x = 6 y = 7 5x + 7y = 5(6) + 7(7) = 30 +49 = 79
89
The x distance is (-2-(-8)) = 6 The y distance is (-1-(-7)) = 6 The point to point distance is from Pythagorean theorem square root of (x squared +y squared) = 8.485
If you mean: x squared + y squared = 26 and x + y = 6 Then it works out that: y = 1 or 5 and therefore x = 5 or 1
General formula for a circle is X squared + Y squared = radius squared. So the answer would be x squared + y squared = 2.64575131 squared
X^2 + Y^2 = 36 Y^2 = 36 - X^2 Y = (+/-)sqrt(36 - X^2) A circle. X = (+/-) 6 Y = (+/-) 6
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
If: y = x^2 -10x +13 and y = x^2 -4x +7 Then: x^2 -10x +13 = x^2 -4x +7 Transposing terms: -6x +6 = 0 => -6x = -6 => x = 1 Substituting the value of x into the original equations point of contact is at: (1, 4)
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
-6
it is (x-y)(x-y) :)
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
no you smell
