Select the correct statement about the function represented by the table A. It is an exponential function because the factor between each x- and y-value is constant.
B. It is a linear function because the difference between each x-and y value is constant.
C. It is a linear function because the y-values increase by an equal difference over equal intervals of x-values.
D. It is an exponential function because the y values increase by an equal factor over equal intervals of x-values.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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
