Show your work please.
the expression √x < 9 (x >0) is equivalent to which of the following:
a) x < 81
b) x < 3
c) x < 9
√8 /3 + √18/2
find the x and y intercepts of the line: 2y-4x+4=0
find the slope of the line: 2y-4x+4=0
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.
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
Your equations seems to be (hard to read) 2y - 4x + 4 = 0
First, simplify by dividing by 2:
y - 2x + 2 = 0
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?
