2x + y = 15
x = 15 - 2y
is it no solution?

It has a solution.

Step-by-step explanation:

Step 1: Rearrange 1st equation into slope-intercept form

2x + y = 15

y = 15 - 2x

Step 2: Rearrange 2nd equation into slope-intercept form

x = 15 - 2y

2y + x = 15

2y = 15 - x

y = 15/2 - x/2

Step 3: Rewrite systems of equations

y = 15 - 2x

y = 15/2 - x/2

Since the two lines are not parallel, they will have a solution.

center= (-2,0)

radius= sqrt2/2

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 %
