Answer:
b) (0,infinity)
Step-by-step explanation:
You can look at the graph and see it starts when x=1, and continues forever in the positive direction.
we are given
we can multiply -1 on both sides of second equation
we can see that
both equations becomes same
so, they are coincident............Answer
Answer:
B
Step-by-step explanation:
3 -4 | 2
0 -1 | 7
3/2 -2 | 1
R1/3 ----> R1 (divide Row 1 by 3)
1 -4/3 | 2/3
0 -1 | 7
3/2 -2 | 1
R3 - 3/2 R1 -------> R3 (multiply Row 1 by 3/2 and subtract it from Row 3)
1 -4/3 | 2/3
0 -1 | 7
0 0 | 0
R2 / -1 -------> R2 (Divide Row 2 by -1)
1 -4/3 | 2/3
0 1 | -7
0 0 | 0
R1 + 4/3 R2 --------> R1 (Multiply Row 2 by 4/3 and add it to Row 1)
1 0 | -26/3
0 1 | -7
0 0 | 0
In the case that a scientist cools three gases in an experiment, the change in temperature will be negative for the experiment. This is because cooling results in a temperature lower than the original temperature. For example, a gas originally at 25°C when cooled to 20°C has a temperature change of -5°C.
