The x-axis goes left and right, the second coordinate is on the y-axis.The y-axis goes up and down.Positive numbers go up or right (depending on the axis). Negative numbers go left or down.Quadrant I gets (+,+); quadrant I is above and to the left of the y-axis.Quadrant IV gets (+,-); quadrant IV is below the x-axis and to the right of the y-axis. (5,4) is in quadrant I.(-5,4) is in Quadrant II. (-5,-4) is in Quadrant III. (5,-4) is in Quadrant IV.
Answer:
14d + 12c -4
Step-by-step explanation:
Option 4. x>2 should be an open circle on 2 going right. x<=-2 should be a closed circle on -2 going left. Remember, < equals open circle and <= equals closed circle.
Check the picture below.
so notice, their perimeter is the same, because the perimeter is just one rod anyway, and all rods are the same length, thus
