Answer:
1,5
Step-by-step explanation:
Marie states that any integer greater than 4 will always get an even number of factors.
This can be proven wrong by (for example) 12.
12 has these factors:
1 x 12
2 x 6
3 x 4
12 has an ODD number of factor pairs.
Another example is 28.
28:
1 x 28
2 x 14
4 x 7
28 has an odd number of factor pairs.
I hope this helps!
Answer:
the absolute value inequality in the form |x-b|c that has the solution set x≤−9 or x≥−5. lol jk
Step-by-step explanation:
|x−b|=c
Since we need three conditions that need to be met, we will opt for presenting three different expressions as a solution.
Case 1
One solution: x=−9
One expression that satisfies this condition is
(c = 0, b = -9 )
|x + 9|=0
|-9 + 9|=0
Case 2
All numbers such that x≤5
The solutions that satisfy this case can be found in the attached picture below, (they were obtained with a mathematical solver.)
Case 3
All numbers such that x≤-14
i pretty sure this is it.
Answer: she has 17 CDs now.
Step-by-step explanation:
The total number of CDs that Chen had initially is 17.
She gives 2 to her brother. This means that she would be having
17 - 2 = 15
She buys 4 more. It means that she would be having
15 + 4 = 19
Her brother gives her 1. So the number that she has is
19 + 1 = 20
she gives 3 to her best friend. Therefore, the number of CDs that Chen has now is
20 - 3 = 17
