Recall that
Take it one piece at a time. For
, we can scale
by -5:
If we shift the argument by 1 and scale by -5, we have
so if we subtract this from
, we'll end up with
For the next piece, we can add another scaled and shifted step like
so that
For the last piece, we add one more term:
and so putting everything together, we get
:
33tweets*x=total number of tweets, where x=days spent tweeting.
If you know the rugs sell for 8$ per square foot and the total spend was $432. You divide 432 by 8 to find the total number of square foot of the rug. Which is 54. To find total square foot you find the area. So the area of a rectangle is L*W. So 54 = 9*width. So just divide 54 by 9 and you get the width of the rug. The width is 6 foot. Now you check. A nine by 6 rugs square foot is 54. and then times by 8 and you get 432 total. So you know the rug is 6 foot wide. :)
Answer:
(m − 3) (m + 2)
Step-by-step explanation:
m² − m − 6
To factor a quadratic ax² + bx + c, you can use the AC method.
1. Multiply a and c.
2. Find factors of ac that add up to b.
3. Divide the factors by a and reduce.
4. The denominators are the coefficients, the numerators are the constants.
Here, a = 1, b = -1, and c = -6.
1. ac = -6
2. Factors of -6 that add up to -1 are -3 and 2.
3. -3/1, 2/1
4. Factors are m − 3 and m + 2.
m² − m − 6 = (m − 3) (m + 2)
