Solve following equations. (a)   x 2 -100 = 0  (b) 25 y 2 - 3 = 0 Solution There actually isn't all that much to these problems.  To use the square root property a

Radical expressions, square root of 18

square root of 18

Solving by substitution, x=y=3 , 2x-y=5

x=y=3 , 2x-y=5

Parallel and perpendicular lines, so I''m having trouble. I honestly don''t...

so I''m having trouble. I honestly don''t under stand this. Y=4x+5. y=-1/4x+4 they want me to tell whether the line is parallel, perpendicular or neither I don''t know how.

you can use the equation -b +or- Square root of bsquared - 4(a)(c)over 2a. But if you number for b is b is negative it will become positive??? And if the number was + it will Beco
