<h2>Answer:</h2>
  • The system of equation has a unique solution or one solution.

Option: A is the correct answer.

              A.  (-2,1)

<h2>Step-by-step explanation:</h2>

The solutions of the system of the equation are the possible points of the intersection of the two lines.

By looking at the graph of the functions the two lines are not parallel and the graph intersect at just one point.

Hence, the system of equations has just one solution or unique solution.

The system of equations is:

y=\dfrac{1}{2}x+2

and

y=-2x-3

The x-value of the point of intersection of two lines is calculated by equating both the lines i.e.

\dfrac{1}{2}x+2=-2x-3\\\\i.e.\\\\\dfrac{1}{2}x+2x=-3-2\\\\i.e.\\\\\dfrac{5}{2}x=-5\\\\i.e.\\\\x=-2

and when x= -2 then the value of y from first equation is:

y=\dfrac{1}{2}\times (-2)+2\\\\i.e.\\\\y=-1+2\\\\i.e.\\\\y=1

Hence, the solution is:

                       (-2,1)

I believe that the answer is 1845




the surface area of the cube is 1350

the surface area of the pyramid is 495

the total surface area is :
1350 + 495 = 1845



good luck
