Answer:
2a2 • (a + 1) • (a - 3)
Step-by-step explanation:
i) Plan A: 21/0,12 = 175 <min of calls>
Plan B: 15/0,14 ≈ 107 <min of calls>
=> 2 plans cost the same 107 min of calls
ii) The cost when 2 plans cost the same:
- Plan A: 107 × 0,12 = 12,84$ ≈ 13$
- Plan B: 107 × 0.14 ≈ 15$
Answer: i) 107 ii) A: 13$ B: 15$
To solve this, you need to plug in the numbers for <em>h</em>.
-4(-12) ≥ 8 48 ≥ 8 yes
-4(-7) ≥ 8 28 ≥ 8 yes
-4(-5) ≥ 8 20 ≥ 8 yes
-4(-3) ≥ 8 12 ≥ 8 yes
-4(-2) ≥ 8 8 ≥ 8 yes
-4(-1) ≥ 8 4 ≥ 8 no
-4(1) ≥ 8 -4 ≥ 8 no
-4(3) ≥ 8 -12 ≥ 8 no
-4(8) ≥ 8 -32 ≥ 8 no
Hope this helped!
