Answer:
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
Step-by-step explanation:
A square matrix is where the number of rows is equal to the number of columns like order 2x2, 3x3, 4x4, 5x5 etc.
Given options are:-
A) A shoe salesperson wants to use an augmented matrix to represent the quantity of children’s shoes and adult shoes sold at his store for two days.
It is 2x2 times 2x1 = 2x1 matrix.
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
It is 6x1 times 1x6 = 6x6 matrix.
C) A student wants to write a coefficient matrix representing a linear system with two equations and three unknowns.
It is 2x3 times 3x1 = 2x1 matrix
D) A teacher wants to write an augmented matrix representing a linear system with four equations and four unknowns.
It is 4x4 times 4x1 = 4x1 matrix.
Hence option B is correct.
Line symmetry this is because if you cut a straight line down the middle it would be the exact same size

Answer:
Step-by-step explanation:
Parent function has been given as,
f(x) = x²
If the parent function is reflected across x-axis,
g(x) = -f(x)
= -x²
Further this function is vertically stretched by 2 units then the new function will be,
e(x) = -2x²
Therefore, parent function 'f' is reflected across x-axis and vertically stretched by scale factor of 2.
the arrowheads on the line means the line keeps on going and going like the Energizer Bunny and going to infinity, so the domain or extent horizontally will be
<h3>from -∞ to +∞ or ( -∞ , +∞ ).</h3>
