Answer:

Step-by-step explanation:

GI is made up of the segments GH and HI. In other words:

$GI=GH+HI$

We know that GH is 2 and GI is 7. Substitute:

$7=2+HI$

Subtract 2 from both sides:

$HI=5$

So, our answer is B.

And we're done!

What is the inverse of the function F (X) equals 2X +1

Liono4ka [1.6K]

Answer: $f^{-1}(x)=\frac{x-1}{2}$

Step-by-step explanation:

To find the inverse of a function start by replacing f(x) with x and replace the original x with y.

$f(x)=2x+1\\x=2y+1$

Now solve for y

$x=2y+1\\x-1=2y+1-1\\x-1=2y\\\frac{x-1}{2} =\frac{2y}{2}\\\frac{x-1}{2} =y$

Finally, replace y with the inverse of f(x), $f^{-1}(x)$

Please help ASAP <3 Correct answer gets brainliest :3

Goshia [24]

Answer:

1. 1,016 sq. m.

2. 119 sq. m.

Step-by-step explanation:

14 x 18 = 252

18 x 8 = 144

14 x 8 = 112

2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )

504 + 288 + 224 = 1,016 sq m

4 (7 x 5 divided by 2) + (7 x 7) =

7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.

I hope this helps
