Tina worked 5 hours and earned $100. What would happen to her wages earned if she worked for 10 hours? Explain your reasoning as it relates to direct variation. << Read Less

You would 100\5=20. Then 10*20= 200. She earned 200 bucks in 10 hours

step-by-step explanation:

i believe the answer is the polygon, heptagon.

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
