Answer:
x = 16
Step-by-step explanation:
Since the numbers are in ascending order, x is the number with the highest value here.
From the arrangement, we can see that the median (the middle number) is the third number which is 9
The mean is the sum of the numbers divided by their count. So we set up the mean and equate to the median
We have this as;
(1 + 9 + 9 + 10 + x)/5 = 9
29 + x = 5(9)
29 + x = 45
x = 45-29
x = 16
Answer:
(-1, 3) and (1, 5).
Step-by-step explanation:
Remember that graphically, the solutions for a system of equations are all the points where the graphs intersect.
In the graph of the system of equations, we see that the they intersect once at (-1, 3) and again at (1, 5).
Therefore, our two solutions to the system are (-1, 3) and (1, 5).
