2. Solve and check this linear system:
y=-x and 2x+y=3
4. Solve and
2y = 3x +

Step-by-step explanation:

y = -x,y2x+y = 3

y=−x;y(2)x+y=3

y=−x;y=−2x2+3

d? maybe

step-by-step explanation:

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 %
