Question: 8.) Solve the system of equations. 4x+5y=3 2x+y=0 9.) A possible step toward solving these equations by addition could be : 4y-6x=11 -8x-4y=13 10.) Given the coordinate points A(2,4), C(3,6), and F(4,8), which equation proves that point C lies on the line AF? 11.) From this trinomial you can deduce that: x to the second power - 6x + 9=0 12.) Factor the polynomial completely. 49s+7rs - 21 - 3r 13.) Factor completely. 12x to the second Power + 13x+ 3

8.) Solve the system of equations. 4x+5y=3 2x+y=0 --> x=-.5; y= 1; 9.) A possible step toward solving these equations by addition could be : 4y-6x=11 -8x-4y=13 --> -14x = 24 10.) Given the coordinate points A(2,4), C(3,6), and F(4,8), which equation proves that point C lies on the line AF? --> d(A,C)+d(C,F)=d(A,F) 11.) From this trinomial you can deduce that: x to the second power - 6x + 9=0 --> x = 3 12.) Factor the polynomial completely. --> 49s+7rs - 21 - 3r = 7s(7+r) - 3(7+r) = (7s-3)(7+r) 13.) Factor completely. 12x^2 +13x +3 = (4x+3)(3x+1)

Just don't tweet about her.Also tell her that she is invading your privacy and tries to cause problems when you have nothing to hide.Your mom is the one who should decide if you are doing anything wrong.
