Answer:

C. -1

Step-by-step explanation:

f(x) = 2/ (-x-1)

As we can see, f(x) is a fraction with two components: numerator (2) and denominator (-x-1).

According to the theorem, the fraction only exists when its denominator is different from 0.

So that in this situation, (-x-1) has to be different from 0

- x - 1 ≠0

=> - x≠ 1

=> x ≠ -1

So that if x = -1, (-x-1) = 0, making the fraction not exist.

So the input is not allowed is x = -1

Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m

arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

$OB = 30$ --- Jack

$AB = 78$ -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

$AB^2 = OA^2 + OB^2$

This gives:

$78^2 = OA^2 + 30^2$

$6084 = OA^2 + 900$

Subtract 900 from both sides

$OA^2= 6084 - 900$

$OA^2= 5184$

Take square roots

$OA = \sqrt{5184}$

$OA = 72$

<em>Hence, Jill drove 72 miles</em>

Find the length of WY

DENIUS [597]

Answer:

WY = 180

Step-by-step explanation:

the diagonals of an isosceles trapezoid are congruent , so

ZX = WY , that is

8y - 4 = 7y + 19 ( subtract 7y from both sides )

y - 4 = 19 ( add 4 to both sides )

y = 23

Then

WY = 7y + 19 = 7(23) + 19 = 161 + 19 = 180
