The answer would be 36 because you plug in the x and 6^2 is 6 Times 6 which is 36

Given equation is $f(x)=6^x$

Now it says to find f(2)

that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)

$f(2)=6^2$

$f(2)=6*6$

$f(2)=36$

Hence final answer is $f(2)=36$

Arrange the equations in increasing order of the value of their solutions.

DiKsa [7]

Answer:

The answer is below

Step-by-step explanation:

1/4x + 5/2x - 2 = 4 - 1/4x

collecting like terms:

(1/4)x + (5/2)x + (1/4)x = 4 + 2

3x = 6

x = 6/3

x = 2

7.9x + x + 4 = -1.1x - 16

collecting like terms:

7.9x + x + 1.1x = - 16 - 4

10x = -20

x = -2

3.2x + 5.7 = -2.5x

collecting like terms:

3.2x + 2.5x = 5.7

5.7x = 5.7

x = 1

10.1x - 1.6x + 44 = -7

collecting like terms:

10.1x - 1.6x = -7 - 44

8.5x = -51

x = -6

Hence the equations in increasing order of the value of their solutions is:

10.1x - 1.6x + 44 = -7

7.9x + x + 4 = -1.1x - 16

3.2x + 5.7 = -2.5x

1/4x + 5/2x - 2 = 4 - 1/4x

I figured out the first question, the second one in lost on.

$\frac{(6-x)}{x^2+3x-28} / \frac{x^2-36}{x^2+5x-36}$

Factor both of the equations, numerator and denominator

$\frac{(6-x)}{(x+7)(x-4)}* \frac{(x+6)(x-6)}{(x+9)(x-4)}$

Cancel the like factors *excuse the zero im just showing you*

$\frac{(0)}{(x+7)} *\frac{(x+6)}{(x-9)}$

Combine frunctions

$\frac{(6+x)}{(x-9)(x+7)}$

x-9=0
x+7=0

Restrictions are 9 and -7
