Step-by-step explanation:
The problem asks to find the values "b" and "c" in a way that
the solutions of the equation |x - b| = c are x= 1/2 and x= -1/3.
It means that "b" is the center of the segment [-
].
This segment has the length
Hence, the half of this length is
.
Therefore, the center of the segment is 
Thus the value of "b" is found: it is b =
.
Then the value of "c" is c =
.
Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.
Step-by-step explanation:
P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.
P = 5+20x
=5+20x•5
= 105
The first mill charges $105 For a 5 meter beam while the second beam charges $110
(k+4) (k-4) the numbers have to multiply up to what ever the number is. so the number is 16 and 4 times 4 is 16. also a pluss and minus makes it into a negative number like the equation
