On a piece of paper, graph y+2>-3x - 3. Then determine which answer
2 answers:
Answer:
option D
Step-by-step explanation:
Subtract 2 from both sides and solve for y
Now graph it using a table
Replace > symbol by == sign
make a table
x y=-3x-5
0 -5
-1 -2
-2 1
Graph the points (0,-5) and (-2,1)
WE have only > symbol so we use dotted line
For shading we use test point (0,0)
Plug in 0 for x and 0 for y
0>-5 True
So we shade the region that contains (0,0)
option D is correct

Answer:
y-determinant = 2
Step-by-step explanation:
Given the following system of equation:
- x + 2y = 5
- x - 3y = 7
Let's represent it using a matrix:
The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:
y-determinant = (1)(7) - (5)(1) = 2.
Therefore, the y-determinant = 2
