What is the additive inverse of x=-1317, and verify -(-x) = x ?

Mice21 [21]

Answer:

1317 is the additive inverse of x = -1317.

Step-by-step explanation:

Additive inverse of a number which when added to the original number gives zero as the result.

Additive inverse of x = -1317

-1317 + 1317 = 0

1317 is the additive inverse of x = -1317.

Verification of -(-x) = x 

L. H. S

-(-x) = -{-(-1317)}

= - 1317

R. H. S

x = -1317

Thus, L.H.S. = R.H.S

-(-x) = x

Verified

Find the inverse of the given function

xenn [34]

For this case, we must find the inverse of the following function:

$f (x) = \frac {5x + 1} {- x + 7}\\x\neq 7$

To find the inverse we follow the steps below:

$y = \frac {5x + 1} {- x + 7}$

We rewrite the denominator:

$y = \frac {5x + 1} {- (x-7)}\\y = - \frac {5x + 1} {(x-7)}$

We exchange variables:

$x = - \frac{5y + 1} {(y-7)}$

We solve for y:

We multiply on both sides of the equation by (y-7)

$x (y-7) = - 5y-1\\xy-7x = -5y-1$

We subtract xy on both sides of the equation:

$-7x = -5y-1-xy$

We add 1 to both sides:

$-7x + 1 = -5y-xy$

We factor for y:

$-7x + 1 = y (-5-x)$

We divide both sides by (-5-x):

$y = \frac {-7x + 1} {- 5-x}$

So, we have:

$f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}$

Answer:

$f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}$

$x\neq -5$

<h2>Writing an linear equation from a given scenario</h2>

Answer:

Choice B

<h3>Step-by-step explanation:</h3>

Please refer to my answer from this question to know more about writing a linear equation from a given scenario: brainly.com/question/24599307

Scenario: A submarine dives $70$ feet per minute.

We let $f$ , be the position of the submarine from sea level as a function of $t$ , the time (in minutes) since the submarine dived.

The given scenario states that for every minute, the position of the submarine decreases (because the submarine is going in a downward direction) by $70$ feet. So $f(t)$ can be defined as $-70t$ .

Now we can select two points for the graph. We can select points $(1, f(1))$ and $(2, f(2))$ .

Evaluation of function:

$f(1) = -70(1) \\ f(1) = -70$

$f(2) = -70(2) \\ f(2) = -140$

Our points are $(1, -70)$ and $(2, -140)$

Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.

So the correct graph is Choice B.

You will need to flip the inequality sign when you subtract 4 from each side in the inequality + 4 < 9. True False

Len [333]

False, you only flip the inequality if you divide out a negative.
