Answer:
Number two: x > -9/2, x < 3/2
Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4
Step-by-step explanation:
Number one:
|4x+5| > 10-2
|4x+5| > 8
4x+5 > 8
-(4x+5) > 8
x > 3/4
x < -13/4
x > 3/4, x < -13/4
(all of these signs are greater than or equal to and less than or equal to)
Number two:
|2x+3| > -6
2x+3 > -6
-(2x+3) > -6
x > -9/2
x < 3/2
x> -9/2, x < 3/2
(all of these signs are correct and not greater than or equal to or less than or equal to)
The product of two even numbers is even.
Let m and n be any integers so that 2m and 2k are two even numbers.
The product is 2m(2k) = 2(2mk), which is even.
Things to think about:
Why didn’t I just show you by using any two even numbers like the number 4 and the number 26?
Why did I change from "m" to "k" ? Are they really different numbers or could they be the same?
Why did I specifically say that m and k were integers?
The product of two odd numbers is an odd number.
Let m and k be any integers. This means that 2m+1 and 2k+1 are odd numbers.
The product is 4mk + 2m + 2k + 1 (hint: I used FOIL) which can be written as
2 ( 2mk + m + k ) + 1 which is an odd number.
£20,900 cuz 22,000-5% is 20,900
So does this mean she earns 23 dollars every hour if so she earns a total of 115 dollars
