Answer:
The answer is D
(x=3, y=8)
Step-by-step explanation:
We want to reduce as many variable as we can so, we can obtain the value for the remaining variables.
Therefore, the first equation y=x+5 multiply it -2., you have -2y=-2x-10 and sum it to the second (2y-x=13), you will obtain the following: -x=13-2x-10.
You have x=3.
If you substitute x=3 in the first equation, you have y=8
Answer:
Stem Leaf
5 | 7
6 | 3 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 9
11 | 4 6 8
Notation: 5|7 means 5.7 and 11|4. means 11.4
Step-by-step explanation:
For this case we have the following data:
5.7 7.2 7.3 6.3 8.1 6.8 7.0 7.6 6.8 6.5 7.0 6.3 7.9 9.0 8.2 8.7 7.8 9.7 7.4 7.7 9.7 7.8 7.7 11.6 11.4 11.8 10.9
The first step on this case is order the dataset on increasing way:
5.7 6.3 6.3 6.5 6.8 6.8 7.0 7.0 7.2 7.3 7.4 7.6 7.7 7.7 7.8 7.8 7.9 8.1 8.2 8.7 9.0 9.7 9.7 10.9 11.4 11.6 11.8
Then we can construct the stem leaf plot like this:
Stem Leaf
5 | 7
6 | 3 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 9
11 | 4 6 8
Notation: 5|7 means 5.7 and 11|4. means 11.4
