Divide both sides by 3:
|4x + 6| = 8
Now remove the absolute value:
4x + 6 = 8
or
4x + 6 = -8
Subtract both sides by 6:
4x = 2
or
4x = -14
Divide both sides by 4:
x = 1/2
or
x = -7/2
Final answer: x = 1/2 or x = -7/2
Answer:
a) 6°C
b) upward
Step-by-step explanation:
a) The range of temperatures is the difference between the maximum and the minimum temperatures. From the graph we can see that:
maximum temperature: 18 °C
minimum temperature: 12 °C
Then:
range of temperatures: 18-12 = 6°C
b) The trend is upward because, given any temperature, the next one is higher.
= (1/3) * 1000 meters
= 333.33 meters
OR
=.3333333 kilometers
