Maria found that 4 bags of leaves weight 6 pounds and 8 bags of leaves weight 12 pounds .She made a graph to help her find the weight of the other bags which ordered pair follows the pattern in the graph

Each bag had weighed about 1 1/2 (or 1.5) pounds.

Step-by-step explanation:

6 divided by 4 should end in a result of the unit weight 1.5 lbs.

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
