Answer:
x ≤ 2
Step-by-step explanation:
-6x - 7 ≥ -19
Add 7 to both sides: -6x ≥ -12
Divide both sides by 6: -x ≥ -2
Divide both sides by -1: x ≤ 2
When you divide by a negative, you have to switch the sign around (hence why I chose to do this in separate steps, so it's clearer)

Answer:
5.5m^2
the area of just the trench is 5.5 m^2
Step-by-step explanation:
The Area of trench only is the total area(trench and garden) minus the Area of garden
Area of trench only = total area(trench and garden) - Area of garden
Area = length × breadth
Substituting the given dimensions;
Total area = 3.5 × 3 = 10.5 m^2
Area of garden = 2.5×2 = 5 m^2
Area of trench only = 10.5 m^2 - 5 m^2
Area of trench only = 5.5m^2
the area of just the trench is 5.5 m^2
H=-5(t^2 - 16t)
H=-5(t^2 - 16t +64)+320
H=-5(t-8)^2 +320
Vertex is at (8, 320)
The max height is 320 m.
