Answer:
Pentane
Explanation:
Answer:
zeros are ±2
Step-by-step explanation:
y = x² - 4
this can be factored into (x+2)(x-2)
if you then set each factor equal to zero you will get zeros of ±2
Answer:
x = 36
Step-by-step explanation:
x - 3y = 12
substitute y for 8
x - 3 * 8 = 12
x - 24 = 12
x = 12 + 24
x = 36

0=b
The Gauss-Jordan elimination method different from the Gaussian elimination method in that unlike the Gauss-Jordan approach, which reduces the matrix to a diagonal matrix, the Gauss elimination method reduces the matrix to an upper-triangular matrix.
<h3>
What is the Gauss-Jordan elimination method?</h3>
Gauss-Jordan Elimination is a technique that may be used to discover the inverse of any invertible matrix as well as to resolve systems of linear equations.
It is based on the following three basic row operations that one may apply to a matrix: Two of the rows should be switched around. Multiply a nonzero scalar by one of the rows.
