Answer: y=-2x-4
Step-by-step explanation:
y=-2x+b
-10=-2(3)+b
-10=-6+b
-4=b
Yes, this is a polynomial, but a special form of a polynomial with just one term which is called a monomial .
It will be 21/40
probability getting both white marbles
3/8×4/10=12/80
probability getting both black marbles
5/8×6/10=30/80
12/80+30/80=42/80= 21/80
