the expression √x < 9 (x >0) is equivalent to which of the following:

a) x < 81
b) x < 3
c) x < 9

simplify:
√8 /3 + √18/2

a) 13√2/6
b) √8+√18/5
c) √8+√18/6
d)5√26/6

find the x and y intercepts of the line: 2y-4x+4=0

find the slope of the line: 2y-4x+4=0

Q1 The options themselves suggest you should square both sides.

Q2 Simplify each surd and then add the fractions by putting them both over the lowest common denominator.

Q3 Substitute x = 0 and solve for y. Substitute y = 0 and solve for x.

Q4 Re-arrange it into the form y = mx + c.

4. Here is the question for find the slop and y-intercept - http://img227.imageshack.us/img227/7...rceptsolve.jpg

EDIT - Didnt see you needed x-ints too, here is the complete work for the bottom two questions. - http://img189.imageshack.us/img189/7...rceptsolve.jpg

5. Your equations seems to be (hard to read) 2y - 4x + 4 = 0

First, simplify by dividing by 2:
y - 2x + 2 = 0
Now, re-arrange:
y = 2x - 2

Since y = mx + b means b = y-intercept, then y-intercept = -2

Now show us how you get the x-intercept...

Btw, do you know what the "m" means?
