-51/7 cannot be simplified
Answer:
2 (3 y - 4) <- Complete answer, but since you only have those choices it's
6 y - 8
Step-by-step explanation:
Simplify the following:
8 y - 2 (y + 4)
Hint: | Distribute -2 over y + 4.
-2 (y + 4) = -2 y - 8:
8 y + -2 y - 8
Hint: | Group like terms in 8 y - 2 y - 8.
Grouping like terms, 8 y - 2 y - 8 = (8 y - 2 y) - 8:
(8 y - 2 y) - 8
Hint: | Combine like terms in 8 y - 2 y.
8 y - 2 y = 6 y:
6 y - 8
Hint: | Factor out the greatest common divisor of the coefficients of 6 y - 8.
Factor 2 out of 6 y - 8:
Answer: 2 (3 y - 4)
Once they are put into standard form:
1. y≤-3/2x+6 Original: 3x+2y≤12
2. y≥6/5x-6 Original: 6x-5y≤30
3. y≥-3/2x+6 Original: 3x+2y≥12
4. y≥6/5x-6 Original: 6x-5y≥30
Answers:
The first graph:

Red line: 6x-5y≥30
The second graph:
Blue line: 3x+2y≥12
Red line: 6x-5y≤30
