Which of the values of [tex]\(z\)[/tex] would NOT satisfy [tex]\(3 - z \geq 7\)[/tex]?



Answer :

To determine which values of [tex]\( z \)[/tex] would not satisfy the inequality [tex]\( 3 - z \geq 7 \)[/tex], we need to isolate [tex]\( z \)[/tex] and find the range of values that do not meet the inequality condition.

### Step-by-Step Solution:

1. Given Inequality:
[tex]\[ 3 - z \geq 7 \][/tex]

2. Isolate [tex]\( z \)[/tex]:
Subtract 3 from both sides of the inequality:
[tex]\[ 3 - z - 3 \geq 7 - 3 \][/tex]
Simplify the left side:
[tex]\[ -z \geq 4 \][/tex]

3. Isolate [tex]\( z \)[/tex] Further:
Multiply both sides by -1. Remember, multiplying or dividing an inequality by a negative number reverses the inequality symbol:
[tex]\[ z \leq -4 \][/tex]

4. Interpretation:
The solution [tex]\( z \leq -4 \)[/tex] means that [tex]\( z \)[/tex] must be less than or equal to [tex]\(-4\)[/tex] in order to satisfy the inequality [tex]\( 3 - z \geq 7 \)[/tex].

To find the values of [tex]\( z \)[/tex] that do not satisfy the inequality, we look for values of [tex]\( z \)[/tex] that are greater than [tex]\(-4\)[/tex]. Any value of [tex]\( z \)[/tex] in the interval [tex]\( -4 < z \)[/tex] will not satisfy [tex]\( 3 - z \geq 7 \)[/tex].

### Examples of [tex]\( z \)[/tex] values that do not satisfy the inequality:
- [tex]\(-3\)[/tex]
- [tex]\(-2\)[/tex]
- [tex]\(-1\)[/tex]
- [tex]\(0\)[/tex]
- [tex]\(1\)[/tex]
- [tex]\(2\)[/tex]
- [tex]\(3\)[/tex]
- [tex]\(4\)[/tex]
- [tex]\(5\)[/tex]

Thus, the values of [tex]\( z \)[/tex] that do not satisfy the inequality [tex]\( 3 - z \geq 7 \)[/tex] are:
[tex]\[ -3, -2, -1, 0, 1, 2, 3, 4, 5 \][/tex]
