Find values that add to 5 and multiply to 6
so the answer would be (x+5)(x+1)
Answer:
46 and 277
Step-by-step explanation:
Given
f(x) =
- 8x - 11 ← substitute x = 3, x = - 4 into f(x)
f(3) =
- 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46
f(- 4) =
- 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277
The independent variable (x) is the domain
Answer:
You should go with the 1st, because it's cheaper.
Step-by-step explanation:
1st plan:
30$ which include 75 mins of free calls and 100 free text messages
25 more mins * 10¢ /min(0.1$/min) = 2.5$
You will pay 32.5$
2nd plan:
(calls)100*0.3$=30$
(text messages)100 * 0.1$=10$
30+10 = 40$
