When comparing fruit weights on a balance scale, Jane notices the following relationships: • 1 orange = 2 bananas • 3 apples = 2 oranges • 1 bunch of grapes = 2 apples Use Jane’s fruit comparisons to determine whether her statements below are true or false. If a statement is false, revise the quantity on the right side of the statement to make it true.

Step-by-step explanation:

Nothing

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

a)(x-2)^2+(y-1)^2=9
