To win a game, Jane must get a sum of 8 on her next two spins of the arrow on the spinner shown below. All the sections of the spinner are of equal size. What is the probability that the results of Jane's next two spins will have a sum of 8?

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

answer: idk

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

answer: 7
