Algebra HELP. is this correct
so 36 is 6,6 so there are two solutions. Am I understanding this correctly

Algebra HELP:(
Use the discriminant to determine how many real-number solutions the equation has. 36x2 - 12x + 1 = 0 How do I do this?

Algebra: pleace check
find the other endpoint of a line segment with the given midpoint (6,4) endpoint ((3, 5). 6= 3/2 and 4 = 5/2 12=6 and 8 = 10 12-6 and 8 - (-10) End Point = (6, 18)

question for Reiny
Reiny, I know that my presentation is poor form. I only know how to work this in MS Word the right way. Is my answer supposed to d=sqrt 34 or d=5.83?

Find the distance between the given points (3, 5) and (8, 2) (8-3)^2 + (2-5)^2 5^2 + -3^2 25 + 9 = 34 sqrt of 34 = 5.83

find the midpoint of the line segment having the given endpoints(0,5) and (0, -8). (0+0/2, -8+5/2) = (0/2,-3/2)= (0,-1.5) P = (0, -1.5)

Find the equation of a line that passes through the point (1,2) and has a slope of 1/3. Show how you found the equation. Would the equation be: y-2=1/3(x-1) Do I need to finish this? I am not sure how.

Algebra: ?
Wouldn't the answer be y=.05x + -1-12
