Answer:
K=-2.5
Step-by-step explanation:
because the line is in the middle of 2 and 3 and is below which means that it is negative
Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long pieces.
The length of the rope = 21 feet
the length of each strip = ![\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20%20)
We need to cut the rope 21 feet into
strips
To find the number of strips we divide 21 feet by the length of the strip
=
= 105
105 strips can Bruce cut from his rope.
hey
let s note a and b the two numbers
we can write
(1) a = 2b - 2
(2) ab = 40
from (2) we can say for b different from 0 that
a = 40/b
replace it in (1)
40/b=2b-2
so
2(b-1)b = 40
b(b-1) = 20
![b^2-b-20 = 0](https://tex.z-dn.net/?f=b%5E2-b-20%20%3D%200)
5 is a trivial solution and as the product of the two solutions is -20 then the second solution is -4 therefore
![b^2-b-20 = 0](https://tex.z-dn.net/?f=b%5E2-b-20%20%3D%200)
<=> (b-5)(b+4) = 0
<=> b = 5 or b = -4
so we have
a= 40/b = 8 and b = 5
or
a = 40/b = -10 and b = -4
(8,5) and (-10.-4) are solutions
do not hesitate if you have any question
thanks
