Answer:
w = -7z/2
Step-by-step explanation:
Our goal is to isolate w
1. subtract 3w from both sides to get 2w+9z = 2z
2. Subtract 9z from both sides to get 2w = -7z
3. Divide both sides by 2 to get w = -7z/2
We cannot simplify further, so this is our answer.
Answer:
x < -7
Step-by-step explanation:
Eliminate parentheses:
3x -12 > 5x +2
-14 > 2x . . . . . . . . . add -2-3x
-7 > x . . . . . . . . . . . divide by 2
Any value of x less than -7 is in the solution set.
It is a function because all the inputs (x values) have one output (y value).
For something to be a function, inputs can only have ONE output, if an input has multiple outputs, it is not a function.
If different inputs have the same output, it is still a function because they don't have the same input value
9.19 times 10 = 91.9
