Solve the homogeneous linear system corresponding to the given coefficient matrix. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, set x4 = t and x2 = s and solve for x1 and x3 in terms of t and s.) [1 0 0 1]
[0 0 1 0]
[0 0 0 0]

(x1, x2, x3, x4) =

Step-by-step explanation:

Given

Required

Determine x1 to x4

First, we write the augmented matrix

Taking the position of each column, we have:

There is no explicit equation for

So: ----- arbitrary variable

implies that:

implies that

implies that

So, we have:

becomes

Let

So:

Where t , s are real numbers

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

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%.
