Answer:

-\frac{1}{\sqrt{2} }.

Step-by-step explanation:

Check images below.

On image 1, we started applying the L'Hôpital's rule for the limit. This rule consist on taking the derivative of the numerator and the denominator, individually and with respect to the variable of interest (in this case is x).

On image 1 we started taking the derivative with respect to x for the numerator.

Then, on image 2 we we started taking the derivative with respect to x for the denominator.

Finally, on image 3 we substituted the result of the derivatives and simplified the result.

What is a negative minus a negative
Rainbow [258]

Answer:

It would be a negative or positive depending on the situation.

Step-by-step explanation:

A negative minus a negative would result in either a positive or negative. For example, -8 - (-9) would be 1 while -8 - (-7) would be -1. If the negative number your subtracting is greater than the number you're subtracting from then it will be positive, vice versa.

The two lines y= 6x+15 and y= mx+4 intersect at x= -2. What is the y-coordinate of their intersection point
taurus [48]

Answer:

The y-coordinate of their intersection point is 3

That is y=3

Step-by-step explanation:

Given two lines are y=6x+15 and y=mx+4

Given that the two lines intersect at x=-2

To find the y coordinate of their intersection point :

Equating the two lines

6x+15=mx+4

6x+15-mx-4=0

6x-mx+11=0

(6-m)x+11=0

At x=-2  (6-m)x+11=0

(6-m)(-2)+11=0

(6-m)(-2)=-11

6-m=\frac{11}{2}

-m=\frac{11}{2}-6

-m=\frac{11-12}{2}

-m=\frac{-1}{2}

m=\frac{1}{2}

Substitute the value m=\frac{1}{2} in y=mx+4 we get

y=\frac{1}{2}x+4

At x=-2 y=\frac{1}{2}(-2)+4

=-1+4

=3

Therefore y=3

Therefore the y-coordinate of their intersection point is 3
