8 - 4(-x + 5)
As you already know, in order to find the equivalent expression to our already given one, we have to simplify it first :)
8 +4x - 20
**Remember that a negative times a negative is always a positive!!**
Add like terms.
4x + (8 - 20)
Simplify.
4x + (-12)
Get rid of parenthesis.
4x - 12
Look at our answer choices.
Our answer is a. 4x - 12

Step-by-step explanation:
A
The sum of a number and 7 is not more than 10
Given answer: x + 7 < 10 , This is false
Reason :Not more than 10 means at most 10, less than or equal to 10 , " or " not greater than 10 "and therefore the correct inequality is written as
x + 7 ≤ 10
B
The product of a number and 4 is at least 20
Given answer: 4X > 20 ---- False
Reason :At least 20 means at no less than 20 " or " greater than or equal to 20 therefore the correct inequality is written as
4X ≥ 20
C
The difference between a 15 and a number is at most 12
Given answer: 15-x>12----False
Reason :At most 12 means " no more than 12 , " " less than or equal to 12 , " or " not greater than 12"therefore the correct inequality is written as
15-x ≤ 12
D
The quotient of a number and 8 is greater than or equal to
Given answer 8x <3 --False
Reason : It clearly stated greater than or equal to 3. Therefore the correct inequality is 8x ≥ 3
Answer: you end up at (2,2)
