Answer:
temperature ≤ 6
Step-by-step explanation:
The highest temperature in February was 6°F. Write and graph an inequality to represent this situtation.
If the maximum temperature was 6, then the temperature reached no more than six, while still reaching 6. Thus, the inequality should be
temperature ≤ 6
The graph would be a filled dot on the 6 pointing towards the left side of the graph (towards the -10 side)
It would be half of the coefficient of x squared added to both sides:
So half of 8 ( the coefficient of 8x) is 4;
The number 4 squared is 16, so you would add that to both sides.
You do this so that you can easily factor the left side: x^2 + 8x + 16 = 4 + 16
(x + 4)(x+4) = 20
Answer:
The explicit formula of that sequence is T - 5
Step-by-step explanation:
Let T represent each term in the sequence. So now try replacing T with each term in the sequence. Like this ;
7 - 5 = 2
2 - 5 = -3
-3 - 5 = -8
hope this helps
Answer:
160,000
Step-by-step explanation:
120,000 + 0.2(120,000)=120,000+24,000=144,000
144,000 were both populations in 2015.
x-0.1x = 144,000
0.9x=144,000
x=160,000
The Population of City Y in 2010 was 160,000
