When x equals -3 then y equals?
It depends on how y depends on x.
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
If an equation of variation where y varies directly as x and y equals 15 when x equals 5 find when x equals 19?
y = 3x y = 3*19 = 57
What is the reflection for y equals -x?
its so easy work it out your self
What transformation is (x y)(y x)?
It is reflection in the line y = x.
Which graph shows a reflection across the x-axis?
y = -f(x) is a reflection of y = f(x) in the x axis.
What single transformation is equivalant to a reflection in the y axis followed by a reflection in the x axis followed by another reflection in the y axis?
reflection in the x-axis
What is the answer for y equals x?
x equals y
How does a reflection across the y axis change the coordinates of a point?
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
What algebraic property is 8 equals x and x equals y?
Transitive property: If 8 equals x and x equals y, then 8 equals y.
What is y equals x plus 2 when x equals -1 and y equals 5?
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
What the results of x plus 2y-2x-y equals x equals?
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
If x equals 3 and 3 equals y then?
x=y
What are geometric transformation?
shown on graphs . 3 types : translation , rotaation , reflection x , y - -x ,y = reflection over y axis x,y- y,-x = reflection over x- axis translation= x,y - x+ or - horizontal change , y+ or - vertical change Perfect reflection= x,y - y,-x 180 degree rotation = x,y - -x , -y 90 degree clockwise rotation=x,y - y , -x 90 degree counter clockwise rotation = x,y - -y,x when graphing transformations , label the new image points as primes . When theres more then one prime , up the amount. Ex: A(1,0) becomes A'(A prime) (-1,0) hope this helps!
