Hello :
$f(x) = 8x$
let : $y=8x$
so : $x= \frac{1}{8} y$
<span>the inverse of </span> $f(x)$ is : $g(x) = \frac{1}{8} x$

Rishan is building a number 3091 using Place-value blocks. There are no thousands block. How many hundreds blocks can he use ins

satela [25.4K]

Given:

The number is 3091.

To find:

The number of hundreds blocks if there are no thousands block.

Solution:

The given number is 3091.

It can be written as:

$3091=3000+0+90+1$

$3091=3\times 1000+0\times 100+9\times 10+1\times 1$

$3091=3\ Thousands+0\ Hundreds+90\ Tens+1\ Ones$

There are no thousands block. So,

$3000=30\times 100$

$3000=30\ Hundreds$

Therefore, the number of hundreds blocks in 3091 is 30.

Solve with matrices. <br><br> 5x -3y = 18 and 2x + 7y = -1

muminat

We'll use Cramer's rule for 2 equations:

ax + by = e

cx + dy = f

5x -3y = 18 a=5 b=-3 e=18

2x + 7y = -1 c=2 d=7 f=-1

denominator determinant (dn) = (a * d) - (c * b) = 5 * 7 - (2 * -3) = 41

x = [(e * d) - (f * b)] / dn

[18 * 7 - (-1 * -3)] / 41 =

123 / 41 = 3

y = [(a * f) - (c * e)] / dn

= (5 * -1) -(2 * 18) / 41 =

-41 / 41 = -1

Consider the function f(x) = 9^x. Which statement MUST be true? A) f(4)/f(1) = f(8)/f(5) B) f(4)·f(1) = f(8)·f(5) C) f(4) − f(1)

shtirl [24]

Step-by-step explanation:

the true answer is (A)

the right side : 9^4 / 9^1 = 9^3

the left side : 9^8 / 9^5 = 9^3

two side are equal

consider the following.find formula simplify answer .Find the domain for the formula and round answer to two decimal places if n

Elanso [62]

The sum of functions is given as:

$(f+g)(x)=f(x)+g(x)$

In this case we have:

$(f+g)(x)=5x+\sqrt[]{x-1}$

The domain of the functions is any number that makes the squared root a real number, then:

$\begin{gathered} x-1\ge0 \\ x\ge1 \end{gathered}$

Hence the domain of the functions is:

$\lbrack1,\infty)$
