Answer:

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

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

SO

\frac{y_{1}- y_{2}}{x_{1}- x_{2}} \\\\=\frac{2-0}{-2-2}

=-\frac{1}{2} this is your slope

so now your equation is y=-\frac{1}{2} x but it isnt done yet if we plug in one of the points we will find the y- intercept.

SO we find our y-intercept is 1 so that makes our equation y=-\frac{1}{2} x+1

Hope this helps!

Pls make brainliest :)

Answer:

D

Step-by-step explanation:

step 1: find the slope

slope is 2/-4 = -1/2

then plug in the value for x to y, you get +1 for the y intercept

then it becomes y=-1/2x + 1

I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!

Each of the linear factors occurs precisely once, so the sign of the given rational expression will change at each of the points where one of the linear factors is zero. That is at:

x

=

−

3

,

−

1

,

2

,

4

Note that when

x

is large, the

x

2

terms will dominate the values of the numerator and denominator, making both positive.

Hence the sign of the value of the rational expression in each of the intervals

(

−

∞

and

(

)

follows the pattern

. Hence the intervals

(

)

and

(

,

4

)

are both part of the solution set.

When

x

=

−

1

or

x

=

4

, the denominator is zero so the rational expression is undefined. Since the numerator is non-zero at those values, the function will have vertical asymptotes at those points (and not satisfy the inequality).

When

x

=

−

3

or

x

=

2

, the numerator is zero and the denominator is non-zero. So the function will be zero and satisfy the inequality at those points.

Hence the solution is:

x

[

−

3

,

−

1

)

∪

[

,

vichka [17]
The area of a regular octagon is given by:
 A = (4) * (L) * (ap)
 Where,
 L: side
 ap: apotema
 Substituting values we have:
 A = (4) * (19) * (16)
 A = 1216 square inches

Sarah's new puppy weighed 5 2/7 pounds. After a month it had gained 5 7/10 pounds.
oksian1 [2.3K]

Answer:

769/70

Step-by-step explanation:

5 2/7 = 37/7

5 7/10 = 57/10

The lowest common multiple is 70

37*10/(7 * 10) = 370/70

57/10 = 57*7/(7*10) = 399/70

Now add

370/70 + 399/70

769/70

Is 769 prime? I think it might be.

Yes it is.
