133 adult tickets were sold.
Step-by-step explanation:
Given,
Total tickets sold for school play = 399
Let,
x represent the number of children tickets sold.
y represent the number of adult tickets sold.
According to given statement;
x+y=399 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 3

Answer:
EF = 6
Step-by-step explanation:
Using the secant- secant power theorem, that is
GF × GE = GH × GS
4(4 + 2x) = 5(5 + x) ← distribute both sides
16 + 8x = 25 + 5x ( subtract 5x from both sides )
16 + 3x = 25 ( subtract 16 from both sides )
3x = 9 ( divide both sides by 3 )
x = 3
Then
EF = 2x = 2 × 3 = 6
Answer:
f(-8) = -512, f(8) = 2
Step-by-step explanation:
Substitute x = -8 and 8 into the function, taking into account the rules of the function.
For x = -8, x < 0 so the value is equal to the cube of -8, which is -512.
For x = 8, x > 0 so the value is equal to the cube root of 8, which is 2.
