Answer:
f-1(x)=-
x-
Step-by-step explanation:
First, switch f(x) to the variable "y".
y=-
x-8
Next, swap "x" and "y" with each other.
x=-y-8
Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...
2x=-3y-16
Now move -16 to the left side.
16+2x=-3y
To get "y" by itself, lets divide each side by -3. Our result is...
y=-x-
To finish the problem off, replace y with f-1(x) and your complete answer will be...
f-1(x)=-x-
The amount he should pay for 5 pounds of mushrooms is $3.6
<u>Step-by-step explanation:</u>
Given data is that,
Bowser bought 6 pounds of mushrooms at a rate of $4.32
At the same rate, determining that how much he should pay for 5 pounds of mushrooms is given by the rate formula.
Rate = total cost / total number of mushrooms
Now, Rate = 4.32 / 6
Let us assume, the cost for 5 pounds as 'x' dollars.
Therefore, Rate = x / 5
<u>To find the value of x, compare both the rates :</u>
⇒ 4.32 / 6 = x / 5
bringing 5 to the left side of the equation,
⇒ (4.32×5) / 6 = x
⇒ x = 21.6 / 6
⇒ x = 3.6 dollars
The amount he should pay for 5 pounds of mushrooms is $3.6
