Answer:
8/15
Step-by-step explanation:
there are 8 yellow marbles and 15 total marbles
Y=mx+b change the equation to solve for m instead. first subtract b on both sides
y-b=mx then divide both sides by x
(y-b)/x=m
m=(y-b)/x
Undefined as the line is parallel to y axis ie; x=3
When you've got a squares bracket, this simply becomes the bracket twice, therefore, (r+s)2 becomes (r+s)(r+s)
You've then go to use FOIL, and this gives you r^2+rs+sr+s^2, and this cannot be simplified any further.
Therefore, the product of this is r^2 + s^2 + rs + sr
Hope this is what you're looking for :)
