Apicture is photocopied by using a scale factor of 2. each side of the photocopy of the picture is
enlarged by a factor of 2.
enlarged by a factor of one-half.
reduced by a factor of 2.
reduced by a factor of one-half.

Each side of the photocopy of the picture is  enlarged by a factor of 2.

Step-by-step explanation:

A picture is photocopied by using a scale factor of 2.

This actually means that the dimensions of the picture are multiplied by a factor 2.

For example, if the width and the height of a photograph are w and h respectively and when photocopied by using a scale factor of 2, then the final width and height of the copy will become 2w and 2h.

Hence, each side of the photocopy of the picture is enlarged by a factor of 2. (Answer)

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
