<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)

How to solve 16 * 12.5
Mariana [72]

Answer: 200

Step-by-step explanation:

First I would do it like this.

12.5

X. 16

—————-

6 times 5 is 0, carry the 3, 6 times 2 is 12 and add 3 from the other which is 15, put the 1 from the 15 to the one next to the 12. 6 times 1 is 6 plus 1 is 7 which now you have 750. 5 times 1 is 5, 2 times 1 is 2, 1 times 1 is 1. It should look like this now.

12.5

X 16

—————

750

+ 1250

——————-

Which is 8750 but wait. Where is the decimal? Well, there is only one number behind the decimal so it is 875.0 or 875.

9(3+5)

if you go through each answer choice you will notice that none of the rest are right 

8(3+6) = 24 +48
8(19 +37) = 152 + 296
9(18 +36)= 162 +324
