Answer:
c. 2b - 3
Step-by-step explanation:
Simplify the following:
-2 b + 4 + 4 b - 7
Grouping like terms, -2 b + 4 + 4 b - 7 = (4 b - 2 b) + (4 - 7):
(4 b - 2 b) + (4 - 7)
4 b - 2 b = 2 b:
2 b + (4 - 7)
4 - 7 = -3:
Answer: 2 b + -3
Answer:
- <em>An integer is not negative if and only if it is not less than zero.</em>
Step-by-step explanation:
Observing each statement individually:
- <em>An integer is negative if and only if it is not less than zero</em>
A number that is NOT less than 0 is greater than zero. Negative numbers are less than 0, so this is clearly incorrect.
- <em>An integer is not negative if and only if it is less than zero.</em>
A number that is NOT negative is positive. Positive integers are integers greater than zero, so this is also incorrect.
- <em>An integer is not negative if and only if it is not less than zero.</em>
A number that is NOT negative is positive. A number that is NOT less than zero is greater than zero, or positive. This statement is correct.
- <em>An integer is less than zero if and only if it is not negative.</em>
A number that is less than zero is negative, and this statement claims that a number less is only less than zero if it is NOT negative. This is incorrect.
