10. Solve the inequality.

–8 ≤ 2x – 4 < 4

A. –2 ≤ x < 4

B. –6 ≤ x < –2

C. –2 ≤ x < 0

D. 0 ≤ x < 6

The Answer is A

Step-by-step explanation:

-8 < 2x-4<4

2x-4<4

-8+4< (2x-4)+4

(2x-4)+4 <4+4

In order to solve these simultaneous inequalities, we need to write them as two separate inequalities, and find the values of x that satisfy both of them.

2x-4<4 In order to solve this linear inequality, we need to group all the variable terms on one side, and all the constant terms on the other side of the inequality.

For example,

- term -4 , will be moved to the left side.

Notice that a term changes sign when it 'moves' from one side of the inequality to the other.

The result is:

A

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

assuming you mean addition: addition and subtraction are reverse operations.
