Given point A(−2,3). State the coordinates of the image of A under the composition T(−3,−4) o r(x-axis) .
A'(2,3) -> A"(-5,-7)
Solve for x and y
Corresponding angles are equal
Linear angles are supplementary
Solve for x and then find the perimeter of the triangle.
x = 2 and 10, 2 is not a solution because it leads to a zero length for a side and a negative length for another side.
So x=10 is the solution which gives a perimeter of 24 units

What are the first names of Ms Hawkins and Mr Starks children?
Nicolas, Joseph and Elias
This man is known as the Father of Geometry. He was born around 325 BC and very little is known about his life. He wrote the Elements which is a collection of 13 books and is considered the most successful and influential mathematical text book ever written. Here is an image of him: What is his name?
