Answer:
20 inches
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (4, 6, 30) as shown below:
Next we cross multiply. We multiply 4 and 30, and we multiply 6 and <em>x</em>.
Now, lets put the values above back into the equation:
Our last step is to divide 120 by 6 to get <em>x </em>by itself.
The answer is 20 inches.
Answer:
B .4
Step-by-step explanation:
Hope this is your answer
Inverting a function is equivalent to solve the equation x = f(y) for the variable y.
Take the function:
y = ∛(x – 2) + 6
Switch x and y, and then solve the equation for y:
x = ∛(y – 2) + 6
x – 6 = ∛(y – 2)
∛(y – 2) = x – 6
Cube both sides:
[ ∛(y – 2) ]³ = (x – 6)³
y – 2 = (x – 6)³
y = (x – 6)³ + 2 <——— and there it is, the inverse function.
