Find the linear approximation of the function \(f(x) = \sqrt{1-x}\) at a = 0 and use it to approximate the numbers \(\sqrt{0.9}\) and \(\sqrt{0.99}\). (Round your answers to four decimal places.)

L(x) =

\(\sqrt{0.9} \approx\)

\(\sqrt{0.99} \approx\)

L(x) =

\(\sqrt{0.9} \approx\)

\(\sqrt{0.99} \approx\)

The equations \(y=-x+4\) and \(y=12x−8y= 21x−8\) form a system of linear equations. The table below shows the y-value for each equation at six different values of x.

\(xy=−x+4y=12x−804−822−740−66−2−58−4−410−6−3\)

What can you conclude from the table?

A. The system has one solution, when \(x=0\).

B. The system has one solution, when \(x=4.\)

C. The system has one solution, when \(x=8.\)

D. The system has no solution.

Let B be a \((4\times3)(4\times3)\) matrix in reduced echelon form.

a) If B has three nonzero rows, then determine the form of B.

b) Suppose that a system of 4 linear equations in 2 unknowns has augmented matrix A, where A is a \((4\times3)(4\times3)\) matrix row equivalent to B.

Demonstrate that the system of equations is inconsistent.
