Answer:
Yes, it is a linear expression because the highest power of x is 1.
Answer:
-4x + y + 6z
Step-by-step explanation:
2x + 5y - z + (-6x - 4y + 7z) < distribute positive 1 to (-6x - 4y + 7z)
2x + 5y - z - 6x - 4y + 7z < combine like terms to get the answer
2x - 6x = -4x
5y - 4y = y
-z + 7z = 6z
our new expression is:
-4x + y + 6z we cannot simplify this any further, so this is our answer
Step-by-step explanation:
1a. ( 3, -4)
1b. ( 8, -2)
1c. ( 10, -10)
hope it helps!
