D: x ≥ 0

7 < √x < 8 ⇒ 7² < x < 8² ⇒ 49 < x < 64

Answer: x = 50 or x = 51 or x = 52 or ... or x = 63.

Answer:

see the explanation

Step-by-step explanation:

we have

$A(x)=2x+5$

Find the inverse of A(x)

Let

y=A(x)

$y=2x+5$

Exchange the variables x for y and y for x

$x=2y+5$

Isolate the variable y

$2y=x-5$

$y=\frac{x-5}{2}$

Let

$g(x)=y$

$g(x)=\frac{x-5}{2}$ ------> function inverse of A(x)

<em>Explanation</em>

For x=1

Find the value of A(x)

$A(1)=2(1)+5=7$

The point (1,7) is a solution for A(x)

That means-----> The point (7,1) is a solution for the function inverse g(x)

Verify

For x=7

$g(7)=\frac{7-5}{2}=1$

The point (7,1) is a solution for g(x)

therefore

A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)

What is 4/9 - (-2/9)

Citrus2011 [14]

Hello!

$\frac{4}{9}-\frac{2}{9}$

First you had to used apply rule -(-b)=b

$\frac{4}{9}+\frac{2}{9}$

Since the denominators are equal to it should be combine by the fractions.

$\frac{4+2}{9}$

Then add 4+2=6

$\frac{6}{9}$

$\frac{4}{9}-\frac{-2}{9}$

Finally you had to cancel by the common factor of 3.

$=Answer--->\frac{2}{3}$

Hope this helps! And thank you for posting at here on Brainly. And have a great day! -Charlie :)

Find the value of x. Give your answer in simplest radical form.

yarga [219]

Using the pythagoras theorem for a right-angled triangle:-

x^2 = 13*2 - 9^2 = 88

x = sqrt 88 = 2 sqrt 22
