So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

Now that we've factored our equation, we can use ZPP and break it up:

So, our solutions are:

Answer:
3 + 3/4x
Step-by-step explanation:
it is 3 up and 4 left so y over x for the the slope. mx +b

(b)Probability Distribution of Drawing Pink Marbles

Rx - sx + y = b
WHEN SOLVING FOR X :
rx - sx + y = b
We must get x onto it's own side, so subtract y from both side.s
rx - sx = b - y
Then, factor out x.
x(r - s) = b - y
Then, divide both sides by (r - s).
x(r - s) ÷ (r - s) = b - y ÷ (r - s)
Simplify.
x = b - y / r - s →

WHEN SOLVING FOR Y :
rx - sx + y = b
We need to isolate y, so get rid of everything BUT y on the left side.
Subtract rx from both sides.
-sx + y = b - rx
Then, add sx to both sides.
y = b - rx + sx
