Answer:
-2
Step-by-step explanation:
z - 7 ≥ 0
z ≥ 7
| z - 7 | = z - 7, z ≥ 7
| z - 7 | = -z + 7, z < 7
z - 9 ≥ 0
z ≥ 9
| z - 9 | = z - 9, z ≥ 9
| z - 9 | = -z + 9, z < 9
| z - 7 | = -z + 7
| z - 9 | = -z + 9
|z - 7| - |z - 9|
-z + 7 - (-z + 9)
-z + 7 + z - 9
= -2
Answer:
Step-by-step explanation:
1/2(5x + 12) = 2x - 3
5/2 x + 6 = 2x - 3
5/2 x - 2x = -3 - 6 = -9
5x = 2 x -9 = -18
x = -18/5
Answer:
the area of the parallelogram = base times the height
For the given parallelogram :
x = 8 units, y = 13 units, and h = 11 units
1) If x is the perpendicular to h
So, the base = 8 and the height = 11
So, the area = 8 * 11 = 88 square units
2) If y is the perpendicular to h
So, the base = 13 and the height = 11
So, the area = 13 * 11 = 143 square units
