Slope intercept form is the form of y = mx + b.

e.g.: y = 3x + 2 is in slope-intercept form.

2y = 3/2 x + 5 is not in slope-intercept form.

y = 3/4 x + 5/2 is the slope-intercept form for 2y = 3/2 x + 5.

\(80:x=5\times a\\ x:80 = 1:5a\\ x = 80:5a = 16:a\\ a = 16:x\)

He still has 6 apples!! 

15 x 9

= 10 x 9 + 5 x 9

= 90 + 45

= 135.

I learn maths like this.

7sqrt2 = sqrt(2 x 7^2) = sqrt(98) which is very close to 10. :)

You make things all go to one side and x go to another side to make the subject x.

Example:

Make a the subject.

 \(ax = \dfrac{ab -1 }{2}\\ 2ax = ab - 1\\ 2ax - ab = -1\\ a(2x - b) = -1\\ a =\dfrac{-1}{2x -b}\\ \;\;=\dfrac{1}{b-2x}\)

Good quote Guest, but it should be math related.

\(S = {aP}\)

The level of slippery of the snail will increase when the rain amount increase!! :P So is that snail dangerous walking on the leaf?

-10 + 7x + 24 - 2

= 7x + 24 - 2 - 10

= 7x + 24 - 12

= 7x + 12

Same answer as higgsb

You typed\(\theta1 = 63 \\\theta2 = 38 \\Mass = 25 KG\\ \epsilon Fx = cos 63 (T{}_{}2)- cos 38 (T1) = 0 \\\epsilon Fy = sin 63 (T{}_{}2)- sin 38 (T1) =\)

You didn't finish typing!!

By the way use \\ command to seperate lines.

e.g.: 2 + 2 \\ = 4 will appear as \(2+2\\=4\)
