We can start with:
x + y = N
where
x is the first 3 digit number
y is the second 3 digit number
In order to get the maximum value of N, the digits used must 9,8,7,6,5,4
To maximize, 9 and 8 must be added. This can only happen if 9 is the first digit of the first number and 8 is the first digit of the second number. The same idea is applied to the other digits. So
x must be 975 and
y must be 864
N = 975 + 864 = 1839
When reflecting about the x axis, the x value remains the same and the y value becomes the inverse of the original y value (opposite)
The point (9,2) would become (9,-2)
3 goes into both 3x and 18
Answer:
-3 1/2
Step-by-step explanation:
We have to find the distance between x and z along the y-axis.
This will be: 5 - -6 = 11 units
1/5 of 11 = 1/5 × 11
= 11/5
= 2 1/5
Now add 2.5 to -6
2 1/2 + -6 = -3 1/2
The value of y = -3 1/2
