Answer:

D is the correct answer

Step-by-step explanation:

Since 5x and 4x+1 are both equal to y, we can set them equal to each other as shown below:

5x=4x+1

x=1

Plugging x=1 into y=5x gets us y=5(1)=5

So x=1 and y=5, which is also (1,5)

In your computation, approximate its value as 3.14.

andrey2020 [161]

Answer: d

Step-by-step explanation:

Find the area of the rectangle.

$A=l*w\\A=(15in)(12in)\\A=180in^2$

Find the area of the base of the semicircle.

$A=\pi r^2$

12 in would be the diameter, divide by 2 to get the radius.

$\frac{12}{2}=6$

Plug this into the formula.

$A=(3.14)(6)^2\\A=113.04in^2$

Since we do not have a full circle but a semi one instead, we must divide our result by 2.

$\frac{113.04}{2}=56.52in^2$

Add both areas.

180+56.52=236.52 $in^2$

If F(x) =5x/3 +5

victus00 [196]

Answer:

$f^{-1}(x)=\frac{3(x-5)}{5}$

Step-by-step explanation:

$f(x)=y=\frac{5x}{3}+5\\y-5=\frac{5x}{3}\\3(y-5)=5x\\x=\frac{3(y-5)}{5}\\ => f^{-1}(x)=\frac{3(x-5)}{5}$
