Curve fitting the following application of linear algebra to curve fitting is explained in greater detail in section $3.7 of your text (page 218). (a) determine the equation of a line passing through the points (-1,-2) and (3,2) in the following way. assume the line has equational form and put both data points into equation (1) to get two equations in the two unknowns co and cy. write this system of equations as a matrix equation of the form: ax - b now use any linear algebra technique you like (row reduction on the augmented matrix, cramer's rule, or compute a-b) to solve for the unknowns x (co, c).

Desmond wants to sell his car that he paid $8,000 for 2 years ago. the car depreciated, or decreased in value, at a constant rate each month over a 2-year period. if x represents the monthly depreciation amount, which expression shows how much desmond can sell his car for today? 8,000 + 24x 8,000 - 24x 8,000 + 2x 8,000 - 2xdesmond wants to sell his car that he paid $8,000 for 2 years ago. the car depreciated, or decreased in value, at a constant rate each month over a 2-year period. if x represents the monthly depreciation amount, which expression shows how much desmond can sell his car for today? 8,000 + 24x 8,000 - 24x 8,000 + 2x 8,000 - 2x

The perimeter of an equilateral triangle is 4 cm more than the perimeter of a square and the length of a side of the triangle is 8 cm more than the length of a side of the aware. find the length of a side of the equilateral triangle

Aright triangle can also be a(n) triangle.
