Who is correct and why?
shelby is correct because the line of best fit has a negative slope and the trend shows a decrease in y values as the x values
increase.
shelby is correct because the line of best fit matches the points as closely as possible with a weak correlation.
ashik is correct because the points are a strong correlation to this nonlinear association
ashik is correct because points with a weak correlation can never have linear association.

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
