Answer:

Step-by-step explanation:

I'm going to assume the expression is (r)(s) + 14s

In order to evaluate this expression We'll need to input the values of r and s into the expression.

(6)(1/4) + 14(1/4)

(6/4) + (14/4)

20/4

Find f^-1(x) A B C D

inna [77]

Answer:

D. f⁻¹(x) = 2x + 10

Explanation:

The given is:

$f(x) = \frac{1}{2}x - 5$

To find the inverse, follow the below procedures:

1- Convert f(x) to y.

This will give:

$y = \frac{1}{2} x - 5$

2- Swap the x and y variables.

This will give:

$x = \frac{1}{2}y - 5$

3- Solve for y.

This will give:

$x = \frac{1}{2}y - 5\\ \\ \frac{1}{2}y = x+5\\ \\ y = 2x+10$

4- Replace the y in the above step with f⁻¹(x).

This will give us:

f⁻¹(x) = 2x + 10

Hope this helps :)

The difference between a number and five equals three. Translate this sentence to an equation and then find the

laila [671]

Answer:

the equation will be:

$\mathbf{x-5=3}$

solving the equation we get x=8

Option B is correct.

Step-by-step explanation:

We need to write equation for this sentence:

The difference between a number and five equals three.

Let number = x

So, the equation will be:

$\mathbf{x-5=3}$

Now, solving the equation to find value of x

$x-5=3$

Adding 5 on both sides

$x-5+5=3+5\\x=8$

So, solving the equation we get x=8

Option B is correct.
