Answer:

Step-by-step explanation:

The inequality |4x + 2| < 26 can be rewritten into two inequalities as the | | function can mean multiply by 1 or multiply by -1.

|4x + 2| < 26

= (4x + 2) < 26 or -(4x + 2) < 26

= 4x < 26 - 2 or -4x <26 + 2

= 4x < 24 or -4x < 28

= x < 6 or x > -7

Combining the two:

|4x + 2| < 26

= -7 < x < 6

The answer is C.

(2x+5y-z)+(-6x-4y+7z)

11111nata11111 [884]

Answer:

-4x + y + 6z

Step-by-step explanation:

2x + 5y - z + (-6x - 4y + 7z) < distribute positive 1 to (-6x - 4y + 7z)

2x + 5y - z - 6x - 4y + 7z < combine like terms to get the answer

2x - 6x = -4x

5y - 4y = y

-z + 7z = 6z

our new expression is:

-4x + y + 6z we cannot simplify this any further, so this is our answer
