Which function is the inverse of Fx) = bx?

mojhsa [17]

Answer:

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

Step-by-step explanation:

The given function is

$f(x) = bx$

To find the inverse function, we let

$y = bx$

We interchange x and y to get:

$x = by$

We now solve for y to get:

$y= \frac{b}{x}$

Therefore the inverse function is

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

Will mark brainliest:) helppppp -7x + y = -19 -2x+ 3y = -19 solve the system of equations

Luba_88 [7]

Answer:

X=2, Y=-15

Step-by-step explanation:

-7x+y=-19

-2x+3y=-19

------------------

-3(-7x+y)=-19

-2x+3y=-19

---------------------

21x-3y=57

-2x+3y=-19

---------------------

19x = 38

19x/19=38/19

x=2

now plug 2 into x of the second equation to get y=-15
