Assuming is the inverse of the expression.

as you'd know, we first off do a quick switcharoo on the variables, and then solve for "y", so, let's do so,

\bf \stackrel{f(x)}{y}=x^2-16\qquad inverse\implies \boxed{x}=\boxed{y}^2-16
\\\\\\
x+16=y^2\implies \sqrt{x+16}=\stackrel{f^{-1}(x)}{y}

An experience bricklayer can construct a small wall in 3 hours. An apprentice can complete the job in 5 hours. Find how long it
Over [174]

Answer:

Step-by-step explanation:

If the bricklayer can construct the wall in its entirety in 3 hours, then he can get 1/3 of the job done in an hour.

If the apprentice can get the whole job done in 5 hours, then he can get 1/5 of the job done in an hour. If they both work together on said job, the equation is

\frac{1}{3}+\frac{1}{5}=\frac{1}{x} and now we solve for x. Multiply everything by the LCM to get rid of the fractions. That would be 15x:

15x(\frac{1}{3}+\frac{1}{5}=\frac{1}{x}) and doing that gives us

5x + 3x = 15 and

8x = 15 so

x = 1.875 hours which is 1 7/8 hours which is also 1 hour and 52 1/2 minutes.
