Answer:
A=20,000 m2 per year
Step-by-step explanation:
we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m
V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2
Answer:

Step-by-step explanation:
Given


Required
Find one possible value of x
From the given parameters;
is a possible solution of
where y= 7
Substitute 7 for y

Add 3 to both sides


Divide both sides by 2


The result of the inequality implies that x is less than 5; So, the possible values of x is all real numbers less than 5;
Having said that;
is one possible coordinate of 
Answer: {(5,0), (3,4)}
Step-by-step explanation:
You can apply the Substitution method:
- Solve for y from the second equation.
- Substitute into the first equation and solve for x.
Then:


(Remember that:
)

Substitute the values obtained into one of the original equation and solve for y:

The solution set is: {(5,0), (3,4)}
