X+ y = 12
x - y = 10
what is the value of the x-determinant for the system shown?
a)-22
b)-12
c)-2

Option C is correct

value of the x-determinant for the system is, -2

Step-by-step explanation:

Given the system of equation:

x + y =12

x -y =10

Represents the system of equations in matrix format:

Now, to find the determinant of a matrix.

Formula for the determinant of matrix:

then;

The value of the x-determinant:

Using determinant(D) formula:

Therefore, the value of the x-determinant for the system is, -2

answer:

c 60% on edg

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
