Answer:

x-1 = 0  or x-7 =0

x=1                      or x=7

Step-by-step explanation:

(x-1) (x-7) =0

Using the zero product property

x-1 = 0  or x-7 =0

x-1+1 =0 +1    or x-7+7 =0+7

x=1                      or x=7

Simply the matrix can anyone help
astra-53 [7]
Here, 3m is a scalar that we use to multiply each element of the matrix.

We have 
3m \left[\begin{array}{cc}-5m&2m\\6m&6n\end{array}\right].

We get 
\left[\begin{array}{cc}(3m)(-5m)&(3m)(2m)\\(3m)(6m)&(3m)(6n)\end{array}\right]
which simplifies to
\left[\begin{array}{cc}-15m^2&6m^2\\18m^2&18mn\end{array}\right]

In a rigid transformation, the shape of the image remains the same as the preimage

The correct options are;

Rotation; a → b

Translation: a → d

Reflection over a horizontal line: c → e

Reflection over a vertical line: g → f

Rotation then reflection: a → h

Rotation then translation: e → j

The reasons why the above selections are correct are as follows;

  • Rotation;  Figure <em>a</em> is rotated about a common center to figure <em>b</em> to move from <em>a</em> to <em>b</em>
  • Translation: Figure <em>a</em> can be translated towards the left and then upwards to reach figure <em>b</em>
  • Reflection over a horizontal line: A reflection over a horizontal line is similar to a reflection across the x-axis, therefore an example of a reflection over horizontal line is c → e
  • Reflection over a vertical line: A reflection over a vertical line will turn a left pointing triangle to a right pointing triangle as shown in g → e
  • Rotation then reflection:  The preimage is first rotated about an axis before it is then reflected as seen in the clockwise  rotation figure <em>a</em> about its axis, followed by a reflection across a vertical axis to figure <em>h</em>
  • Rotation then translation: The rotation and translation composite transformation can be seen in figure <em>e </em>which is rotated to point left, and then translated into the position of figure <em>j</em>
