Answer:
The possible values are less than 4 but greater than –4
Step-by-step explanation:
If the absolute value of integer number is less than 4 then it is 0, 1, 2 or 3.
so the possible integer numbers are: -3, -2, -1, 0, 1, 2 or 3.
All of them are greater than -4 and less than 4
2n^2-8n=9
divide by 2
2(n^2-4n) =9
add (4/2)^2 =4 to each side completing the square
(n^2-4n+4 ) =9/2+4
(n-2)^2 = 9/2+8/2
(n-2)^2 =17/2
take the square root of each side
n-2 = +-sqrt(17/2)
add 2 to each side
n = 2+- sqrt (17/2)
Answer:2+ sqrt (17/2),2- sqrt (17/2)
If you take this equation and graph it you get the points (0,-2) (6,0) (-6,-4) and (3,-1)
Answer:
1000 to 9999 are all of the 4-digit counting numbers
1 to 9999 gives 9999 counting numbers, but we are leaving out 999 of them
9999-999=9000 counting numbers that are 4-digit numbers
9000-1800=7200 4-digit numbers that are not multiples of 5
