To solve this problem you must apply the proccedure showb below:
1. You have the following equation:
<span> 2x^2+9y^2=18
2. Dividing the equation by 18, you have:
(x^2/9)+(y^2/2)=1
3. The center is:
[</span>(x-0)^2/9]3^2[(y-0)^2/√2]=1
<span>
(h,k)=(0,0)
The center is (0,0)
4. The vertices are:
a^2=9
a=3
Vertices: (-3,0) and (3,0)
5. The foci is:
c^2=a^2-b^2
c=</span>√7
<span>
The foci is: (-</span>√7,0) and (√7,0)

Answer: Option 'b' is correct.
Step-by-step explanation:
Since we have that
When Demand exceeds supply.
It means money supply is more in the country due to which demand for a good increased more than supply.
It is the situation of inflation.
In this case, price would increase to curb the increase in demand.
For example, if the prevaling price for a particular good is $5, so a person is willing to purchase 10 units as he has $50.
But if the price gets increased and the new price becomes $10, then that person can buy only 5 units from $50.
So, it can reduce the demand and makes it equal to supply.
So, Option 'b' is correct.
Marcus should have substituted -10for b, not 10
Marcus should have subtracted 4(1)(25) in the square root
This equation, when solved correctly, only has one real number solution
So A, C, D
Here is the work hope this helps!
