Matrix question help needed
kramer

The required matrix is:

\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]

Step-by-step explanation:

We need to apply elementary row operation -2R₂+3R₁ tothe matrix:

A=\left[\begin{array}{ccc}-3&5&2\\8&-1&3\\\end{array}\right]

Multiplying Row 2 with -2 and Row1 with 3 and adding,

-9 15 6

-16 2 -6

----------

-25 17  0

After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁

The required matrix is:

\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]

Keywords: Matrices, elementary row operation

Which figure can be transformed into figure P by a translation 2 units to the right followed by a reflection across the x-axis?
Rudiy27

Answer:

Figure M

Step-by-step explanation:

Figure P has vertices at points (-2,4), (-2,8), (-6,8) and (-6,6).

Consider figure M with vertices (-4,-4), (-4,-8), (-8,-8) and (-8,-6).

1. Translate figure M 2 units to the right. This translation has the rule:

(x,y)→(x+2,y),

so

  • (-4,-4)→(-2,-4);
  • (-4,-8)→(-2,-8);
  • (-8,-8)→(-6,-8);
  • (-8,-6)→(-6,-6).

2. Reflect the translation image figure M across the x-axis according to the rule

(x,y)→(x,-y)

Thus,

  • (-2,-4)→(-2,4);
  • (-2,-8)→(-2,8);
  • (-6,-8)→(-6,8);
  • (-6,-6)→(-6,6).
