You should first of all rewrite the equation in slope intercept form. You should get y=2/3x-2. The perpendicular slope is the opposite reciprocal, in this case -3/2. You will use this slope and the point to write your equation in point slope form and then clean this up to get it into slope intercept form. You should get y=-3/2x-6
Xints are where y=0
0=x^2+4x-12
0=(x-2)(x+6)
x-2=0
x=2
x+6=0
x=-6
(x,y)
xints are
(2,0) and (-6,0)
Answer:
looking at it I think B is P from another angle
Since 1 cm = 10 mm
Then 4 cm = 40 mm
so together the amount of people who chose beef should be 4/12 since you must find the greatest commen factor. Then you should add 4/12 and 24 im thinking and you would get 24.3333 but if your looking for a mix number it would be 24 3333/1000
hope this helps!
