Solving a polynomial inequation
Solving the following inequation:
(x - 8) (x + 1) > 0
We are going to find the sign both parts of the multiplication,
(x - 8) and (x + 1), have when
x < - 8
-8 < x < 1
1 < x
Then we know (x - 8) (x + 1) > 0 whenever (x - 8) (x + 1) is positive
We can see in the figure (x - 8) (x + 1) is positive when x < -8 and x > 1
Then
Answer:B

Answer:
Step-by-step explanation:
You can confirm this by working and expanding backwards:
Hope this helps!
Answer:
Step-by-step explanation:
The expression can be fully factored as ...
3·5·(x-3)
Equivalent expressions can be formed by eliminating parentheses to give ...
15x -45
or by combining different pairs of factors:
Of course any of the terms can be broken apart and/or combined in different ways:
= 15(x -2) -15
= (7x -7) + 2(4x -19)
Step-by-step explanation:
To convert decimal number 639 to quinary, follow these steps:
- Divide 639 by 5 keeping notice of the quotient and the remainder.
- Continue dividing the quotient by 5 until you get a quotient of zero.
- Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 639.
- Using the above steps, here is the work involved in the solution for converting 639 to quinary number:
- 639 / 5 = 127 with remainder 4
- 127 / 5 = 25 with remainder 2
- 25 / 5 = 5 with remainder 0
- 5 / 5 = 1 with remainder 0
- 1 / 5 = 0 with remainder 1
Then just write down the remainders in the reverse order to get the answer, The decimal number 639 converted to quinary is therefore equal to :
10024
