Natalie made a graph showing these ordered pairs representing a proportional relationship. (0.5, 2), (4, 16), (6.5, 26)

Which ordered pair would be on the same line as Natalie’s ordered pairs?
(3.5, 12)
(2, 4)
(8, 32)
(12, 36)

answer: idk

step-by-step explanation: sry idk

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
