answer

6.   1/2k-2  

see explanation

Step-by-step explanation:

(6)

multiply each term inside the parenthesis by the fraction outside

= ( × k ) + ( × - 4)

= k + (- 2) = k - 2

(7)

A reminder that the absolute value function always returns a positive value.

The value inside the bars can be positive or negative but the result is always positive.

2 + |- 5 + 4 | = 2 + |- 1 | = 2 + 1 = 3

(8)

A |- 4 - 5 | = | - 9 | = 9

B - | 9 | = - 9 ← does not equal 9

C | - 9 | = 9

D | 9 | = 9

(9)

given 3(2n + 1) + 4(n - 2)

distribute both parenthesis and collect like terms

= 6n + 3 + 4n - 8

= (6n + 4n) + (3 - 8)

= 10n + (- 5) = 10n - 5
