Answer:
Step-by-step explanation:
x²+6x = 18
coefficient of the x term: 6
divide it in half: 3
square it: 3²
add 3² to both sides to complete the square and keep the equation balanced:
x²+6x+3² = 18+3²
(x+3)² = 27
x+3 = ±√27 = ±3√3
x = -3±3√3
Answer: The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given, T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The average rate of change in a function with respect to the independent variable gives the value of change in a particular period.
If average rate of change in T(d) for the interval d = 4 and d = 10 is is 0 , that means nothing has been changed in the number of tickets sold on 4th day and 10th day after the film release.
Hence, the correct statement is "The same number of tickets was sold on the fourth day and tenth day."

Tax is a compulsory amount that is levied by the government on certain goods and services.
Percentage is the fraction of an amount expressed as a number out of hundred. To convert a number from percentage to a number, divide the percentage by 100.
Tax paid = 10% x total bill
$1.10 = 0.1 x b
1.10 = 0.1b
b = 1.10 / 0.1
b = $11

Answer:
256/81
Step-by-step explanation:
a⁻ᵇ = 1/aᵇ
(a/c)ᵇ = aᵇ / cᵇ
1/(c/d) = d/c
then:
(-3/4)⁻⁴ = 1/(-3/4)⁴ = 1/(-3⁴/4⁴) = 1/(81/256) = 256/81
