The required value of the given inverse function f⁻¹(22) will be 7.
<h3>What is an inverse function?</h3>
The inverse function is defined as a function obtained by reversing the given function.
Given that f(7) = 22
To determine the value of the given inverse function f⁻¹(22)
An inverse function's main objective is to show the value that occurs in a specific function value. Which means :
If we have f(x) and f⁻¹(x), then
if f(a) = b then f⁻¹(b) = a
As per the given question, we have
⇒ f(7) = 22 then f⁻¹(22) = 7
Therefore, the required value of the given inverse function f⁻¹(22) will be 7.

Answer:
is know that -x allowed = 2 and x = 1
Step-by-step explanation:
Answer:
A. <u>4</u> trucks will make $80 because 4 × 20 = 80, so they need to wash <u>38</u> cars to make the other $380 because 38 × 10 = 380.
($80 + $380 = $460)
B. <u>15</u> trucks will make $300 because
15 × 20 = 300, so they need to wash <u>16</u> cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)
C. <u>21</u> trucks will make $420 because
21 × 20 = 420, so they need to wash <u>4</u> cars to make the other $40 because 4 × 10 = 40.
($420 + $40 = $460)
D. <u>27</u> trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.
Not sure what to do for letter E. Sorry. I hope the rest makes sense though :)
If he has 18 arrows and is shooting 3 at a time, divide, 18/3 = 6
He can shoot 6 times.
Answer:
C = 40p
Cost for 15 people: 600 dollars
Step-by-step explanation:
The amusement park charges $40 per person.
That can be represented as 40 × <em>P</em> or 40<em>P</em>.
<em>C</em> is equal to the cost of admission for <em>P</em> people.
So, <em>C</em> = 40<em>P</em>
<em />
<em>C </em>= 40<em>P</em>
<em>C</em> = 40(15)
<em>C</em> = 600
The cost of admission for 15 people is 600 dollars.
Hope that helps.
