What transformation is represented by the rule (x y) (y -x)?
It is an anticlockwise rotation through 90 degrees.
What is the algebraic expression for excess of 15 over y equals 10?
y + 15 = 10
What does reflection over the x-axis mean?
(x,-y)
How do you write as a word phrase for each algebraic expressions y over 5 minus 10?
What does the algebraic expression x - 3 / 2 say in words
What is the algebraic expression for 11 more than y?
Y + 11
What is the rule for finding the reflection of a point over the axis?
For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.
Write the rule in algebraic form?
you write it like this (x,y) ----> (-x+4, y-5)
What is an example of an algebraic rule that is not a function?
x2 - y2 = (x + y)(x - y) is an identity, not a function.
What is the algebraic rule for rotating point x and y 90 degrees in an anticlockwise direction?
(x=y) (y=-x)
How do you write Y over 5 in algebraic form?
y/5
What does reflection over the y-axis mean?
Example: if you have a point with the coordinates (2,4), a reflection over the y-axis will result in the point with coordinates (-2,4).
What transformation is represented by the rule (x y) (y -x)?
It is an anticlockwise rotation through 90 degrees.
What is the algebraic expression for excess of 15 over y equals 10?
y + 15 = 10
What is the rule for reflection over y-x?
I never learned a rule for reflection, but the easiest method would be to count the number of points the point of your figure/line from the x- axis or y-axis, and apply the same number onto the other side. That's how I always did it. It you were to just move the whole figure over, that would only be translation! make sure the figure/line makes sense of where it is.
What type of equation is X equals Y over Z?
algebraic
What does reflection over the x-axis mean?
(x,-y)
What are the coordinates of the reflection of (a b) over the y-axis?
They are (-a, b).
