Graph the linear system and determine how many solutions it has: no solution, exactly one solution or
infinitely many solutions. (How do you graph this? Can you provide a graph for this?)
a. x + y = 4
x - y = 2
b. x + 2y = -2
-3x - 6y = 6
c. 2x - 3y = -6
-3y + 2x = 3
Multiplying rational expressions: (I will just write divided by as the operation used)
1. w^3-1/(w-1)^2 * w^2-1/w^2+w+1
2. 19x^2/12y-1 * 1-12y/3x
3. 10x-4x^2/4x^20x+25 * (2x^3-5x^2)
4. a^2-2ab+b^2/a-b T * (a+b)^3/a^2+2ab+b^2
Dividing rational expresseion:
1. x^2+6x+9/18 DIVIDED BY (x+3)^2/36
2. 2x^2-5x-12/6+4x DIVIDED BY x^2-16/2
THIS ONE IS A COMPLEX FRACTION
1. x^2+5x+6/x+2/x+3
