The number of people estimated to vote in an election was 7,000. The actual number of people who voted was 5,600. By what percent did the estimate vary from actual turnout?

%

In the previous election 6,400 people voted. What is the percent decrease in actual voters?

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

what is the question?

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

-1   1/6.   you dont subtract the denominators
