Answer: 4/21
Step-by-step explanation: first convert it to an improper fraction, which would be 21/4
reciprocal means flip the fraction so it’s 4/21
F(a)=-2a^2 - 5a^4
if a=-3
f(-3)=-2(-3)^2 - 5(-3)^4
=(-2*9) - (5*81)
=-18 - 405
=423

Answer:
C)two thirds x + 10 = 21
Step-by-step explanation:
The equation for determining how much it would be paid for the student tickets is shown below:
Given that
The ticket of an adult is $21
Now let us assume the price of the student ticket be x
So two third would be 2 ÷ 3x
And for adult it would be
2 ÷ 3x + 10
Now the equation is
2 ÷ 3x + 10 = 21
So after solving this the option c is correct
And the rest of the options are wrong
