Answer:
12
Step-by-step explanation:
| 4-y| ≥8
Separate into two inequalities, one positive and one negative (remembering to flip the inequality)
4-y ≥8 or 4-y≤ -8
Solve
Subtract 4 from all sides
4-y -4 ≥8-4 or 4-y-4≤ -8-4
-y ≥4 or -y≤ -12
Divide each side by -1, remembering to flip the inequality
y ≤-4 or y ≥12
The smallest positive number is 12
A
Step 1: Simplify both sides of the inequality.
−y+4≥8
Step 2: Subtract 4 from both sides.
−y+4−4≥8−4
−y≥4
Step 3: Divide both sides by -1.
−y
−1
≥
4
y≤−4
It would be the first one... 10:25
10/4=2.5
2.5*10=25
2.5*4=10
