ANSWER

$\boxed {m \ne0}$

EXPLANATION

The given function is

$f(x) = mx + b$

We need to find the inverse of this function,

Let

$y= mx + b$

We interchange x an y to obtain,

$x = my + b$

We solve for y now to obtain,

$x - b = my$

We divide through by m to get,

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

Hence the inverse function is ,

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

For this inverse to exist, the denominator must not be equal to zero,

Thus

$m \ne0$

The correct answer is A.

The number of goldfish in a tank is 19, and the volume of the tank is 52 cubic feet. What is the density of the tank? (5 points)

galina1969 [7]

Answer:

0.22

Step-by-step explanation:

p= m/v

in this problem, we divide 12 goldfishes by 45 cubic feet. This is equal to 0.27 goldfish per cubic feet..This is equal to 0.27 goldfish per cubic feet.

The answer is 0.22

Given the rectangular solid, RS = 6, ST = 3, and SL = 4. Solve for KT.

katrin [286]

First thing is that you need to find the diagonal of the rectangle

but remember is it a horizontal rectangle.

So let's start it :)

d= √6²+3²

d= √36+9

d= √54

d= 6.7082

But wait.. we are not done yet

We need to solve KT

we have 6.7082 which is the base and we have SL=4 which is the height

so with this 2 information we can find KT

KT is the hypotenuse because when you draw the line from K to T you'll see that it is the longest line.

Use the hypotenuse formula which is

C = √a²+b²

Now replace C by KT since we are solving for KT instead of C. Got it ?:)

KT= √6.7080²+4²

KT= 7.81

I do it with decimals so it might be little bit confusing to you but I think you can solve that different ways :)

Well I hope that's help and if not I am so sorry.
