The correct answer is:
Answer:
The answer to your question is in the picture below
Step-by-step explanation:
y + 3/4x < 2
y+ 3/4x = 2
y = -3/4x +2
Interceptions (0,2) and (8/3, 0) It's a dotted line and we are interested in the area below the line
y - 1 ≥ 2x
y - 1 = 2x
y = 2x + 1 Interception, it's not a dotted line with interceptions (0,1) and (-1/2, 0), we are interested in the area up the line.
Answer: Choice B
=====================================
Explanation:
The given matrix is
The numbers to the right of the vertical bar represent the values on the right hand side of each equation in the final answer.
The numbers to the left of the bar represent the x and y coefficients of the equations. The first number of any given row is the x coefficient. The second number is the y coefficient.
For instance, the first row has to indicate the x coefficient is 1, and the y coefficient is 5. We end up with 1x+5y or simply x+5y. Putting everything together, the first equation would be x+5y = 11
Through similar steps, the second equation is 4x-6y = -3
