Math problem A homeowner has two rectangular structures in her backyard. The dimensions of the hot tub are 6 feet by 8 feet. The

Zolol [24]

Answer:

289feet²

Step-by-step explanation:

Area of a rectangle = length x breadth

area of a square = length²

area of the yard that is not covered by the hot tub and fire pit =

Area of the yard - (area of the hot tub + area of the fire pit)

Area of the yard = 20 feet² = 400 feet²

area of the hot tub = 6 feet² x 8 feet² = 48 feet²

area of the fire pit = 7 feet² x 9 feet² = 63 feet²

400 - (48 + 63) = 289 feet²

If f(x) = 6x – 4, then f^-1(x)=

guapka [62]

Answer:

$f^{-1}(x)=\frac{x}{6}+\frac{2}{3}$

Step-by-step explanation:

Given function.

$f(x)=6x-4$

To find the inverse function $f^{-1}(x)$

Step 1:

Replace $f(x)$ with $y$ in the function.

$y=6x-4$

Step 2:

Interchange $y$ with $x$ in the equation.

$x=6y-4$

Step 3:

Solve for $y$ .

We have $x=6y-4$

Adding 4 to both sides,

$x+4=6y-4+4$

$x+4=6y$

Dividing each term by 6 to isolate $y$

$\frac{x}{6}+\frac{4}{6}=\frac{6y}{6}$

$\frac{x}{6}+\frac{4}{6}=y$

Simplifying fractions by dividing the numerator and denominator by their GCF.

$\frac{x}{6}+\frac{4\div 2}{6\div 2}=y$

$\frac{x}{6}+\frac{2}{3}=y$

Thus the equation of $y$ is:

$y=\frac{x}{6}+\frac{2}{3}$

Step 4:

Replace $y$ with $f^{-1}(x)$

$f^{-1}(x)=\frac{x}{6}+\frac{2}{3}$ (Answer)

Thus, we have the inverse function
