Answer:
- temperature is decreasing as time passes
- x-axis
- hot drink temperature (°C)
Step-by-step explanation:
1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.
__
2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.
__
3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.
Answer:
C. 27x-67
Step-by-step explanation:
To simplify, combine like terms meaning variable terms with variable terms and constants with constants.
81x-54x = 27x
-46-21=-46+-21=-67
The expression is 27x-67
Answer:
15 49-cent stamps
Step-by-step explanation:
We can solve this problem with the equations <em>0.49(x) + 0.21(y) = 9.45 </em>and <em>x - 5 = y</em>. Well, 0.49(15) + 0.21(10) = 9.45, so we know that there are 15 49-cent stamps and 10 21-cent stamps. The question is asking for the number of 49-cent stamps, so we can tell Travis bought 15 49-cent stamps.
