say that it is made from delicious cocoa powder, sugar and milk

WRITING(CHOCOLATE BAR)
for the first one perhaps say what chocolate is made from....even include from what country the cacao beans come from

A (4,3) B (3,-3) c (-4,5) Find the slope of AB, BC, and AC. Find the tangent of each angle and their angle measure (inv. tan) using: tan of an angle =m2-m1/1+m1m2 m2 being the slope of the terminal side (measuring counterclockwise) the triangle looks like this c a b

did you not understand my answer before?

did you make sure to put parentheses around the second part after the division sign?

A (4,3) B (3,-3) c (-4,5) Find the slope of AB, BC, and AC. Fond the tangent of each angle and their angle measure using: tanX=m2-m1/1+m1m2 m2 being the slope of the terminal side (measuring counterclockwise)

Algebra
you need to get it into slope intercept form--y=mx+b (m being the slope) to figure out whether they are parallel (having equal slopes) or perpendicular (slopes are negative reciprocals) 2y-x=2 2y=x+2 y=1/2x+1 slope=1/2 y+2x=4 y=-2x+4 slope=-2 -2 and 1/2 are negative ...

using distance formula d of GI= square root of 10-3.1622 twice this is the square root of 40 could be- 6 or 2

college algebra
find a common denominator-x 8x/x -5/x= 2x/x +3/x when you multiply both sides by x you get: 8x-5=2x+3 8x=2x+8 6x=8 x=8/6 x=1 and 1\3

if it is 3/(x-5)=10/(x+2) then the answer is 8 cross multiply= 3x+6=10X-50 56=7x x=8

algebra
is it 3/(x-5) or 3/x -5?

trigonometry
thanks a bunch!

using the law of sines, solve the rest of the triangle: side C=14 side B=4 angle c=145 degrees i got angle b= 9.4 angle a=25.6 side A=10.4 but i didn't know if it was correct
