Answer:
Step-by-step explanation: 8*2x, 8*-14+13=4x-27
16x-112+13=4x-27
16x-99=4x-27
-4x -4x
12x-99=-27
+99 +99
12x = 72
/12 /12
x=6

Answer:
(50000000 ≤ P ≤ 90000000)
Step-by-step explanation:
The chart represents annual profits in millions of dollars. From the chart, the least annual profit is 50 million dollars and that was is the year 2009.
The highest annual profit is 90 million dollars and that was is the year 2012.
The compound inequality representing the annual profits P(in millions or dollars) from 2006 to 2013 would be
(50000000 ≤ P ≤ 90000000)
