Question

Explain how solving -7y > 161 is different from solving 7y > -161

Answer 1

Answer:

here's ur answer dude

Step-by-step explanation:

The article focuses on using an algorithm for solving a system of linear equations. We will deal with the matrix of coefficients. Gaussian Elimination does not work on singular matrices (they lead to division by zero).

Input: For N unknowns, input is an augmented

matrix of size N x (N+1). One extra

column is for Right Hand Side (RHS)

mat[N][N+1] = {{3.0, 2.0,-4.0, 3.0},

{2.0, 3.0, 3.0, 15.0},

{5.0, -3, 1.0, 14.0}

hope it helps

Answer 2

Answer:

Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>
