X+y+z=11, x-y+z=5, x-z=y+1 and solve it by any of the methods: isolation, elimination or determinants. isolation (or back substitution, would be for instance: z = 11-x-y, z=5-x+y, z = x-y-1 and then impose z=z:
11-x-y=5-x+y,
11-x-y=x-y-1,
The first takes you to: 6=2y or y=3, then the second to 12=2x or x=6, so that:
x=6, y=3, z=2.
You can see that it checks out
Answer:
300.5 = 300
Step-by-step explanation:
area= base x height (parallelogram)
area=
(semicircle)
parallelogram: 11 x 20 = 220
semicircle: ![\left[\begin{\frac{22(8^2)}{7}}\right] \frac{1}{2}](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7B%5Cfrac%7B22%288%5E2%29%7D%7B7%7D%7D%5Cright%5D%20%5Cfrac%7B1%7D%7B2%7D)
=> 
=> 100.5
therefore 100.5 + 220 = 300.5-ans.

Answer: you can divide it by 2 and get 2.8 or you can divide it by 8 and get .7 or do 5.6 divided by 7 and get .8 ( I don’t really know what your asking but here you go )
Answer:
A is the correct answer
Step-by-step explanation:
Given: Table of x and y
x : 2 4 6 8
y : 3 4 5 6
Using two point find the slope:
(2,3) and (4,4)
Now we find slope using last two point
(6,5) and (8,6)
Slope is equal. Thus, The given relation is linear.
Hence, The relation represents a linear equation
