1.Simplify the following Expression
a. 5y^2+ 3y – 13 + 6x – 3y + 6y^2

Simplified expression is 11y² + 6x - 13

Step-by-step explanation:

5y² + 3y - 13 + 6x - 3y + 6y² = 11y² + 6x - 13

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

hope this !

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
