    Is this correct: Solve: (x+5)^2 = 3 I get: x = -5 (+/-) sqrt (3) Problem #2 Solve: 5(x-2)^2 = 3 I get: x = 3 (+/-) ((sqrt(3))/(5) No on the second. YOu have take the sqrt5 slso, so x= 2+- sqrt(3/5) correct on the first.

    okay for the first one i/ve done it twice and both times i got 10, not -10. check your work to make sure you did it correctly. for the second one i got 24 so you are correct Directions solve for x. (x)/(x-2)-(x+1)/(x)=(8)/(x^2-2x) The answer i get is :

    direction state : solve each system by addition. if a unique solution does not exist, state whether the system is consistent or dependent. NOw the problem looks like this: 2x+3y=1 5x+3y=16 the answer that I got was this: for variable x = 5 y = -3 which is

    can someone correct this for me please. Directions: Solve the following system by substitution. 5x-2y=-5 y-5x-3 what i received as the solution are : x = - (1)/(5) and y = 2 which it would look like: (-(1)/(5) , 2) correct.

    I have to determine which two equations represent parallel lines. equations are (a) y=(-4)x+2 (b) y=(4)x+2 (c) y= (1/2)x +2 (d) y=(-4)x+3 so the answer would be: A and D yes

    can someone please correct this for me. i have to graph: y = 3/4x + 2 so the points i got for plotting is: (-4,-1),(0,2),(4,5) then i just connect the points to get the line. If they plot on a line the answer is correct. y= 3/4 x + 2 is a line, and all

    can someone correct me: i have to graph i have the inequalities: 3x -6y = 9 x -2y = 3 what i have is the points to plot if my y = -3/2 and my x = 0 therefore: (0,-1.5) and (0,0) No. If y=0, then x=3 . Check that.

    is this correct: solve: 5(x-2)^2=3 My answer: (10 +/- sqrt 15)/(5) looks like you expanded, then used the formula and you got the right answer properly reduced. I think you are getting this!!! I don't want to confuse you but I would have done the

    IS THIS CORRECT NOW. solve by using the quadratic formula. x^2 = -5-5 My answer: x = (-5 +- SQRT (5))/(2) I don't see any x term, so b is zero. sorry it suppost to read that first -5x-5
