Answer:

A dilation preserves angle measures.

A dilation alters the length of line segments by the same proportion.

Step-by-step explanation:

A dilatation is a transformation that alters a figure's size while maintaining its shape and orientation. Each linear measure of the figure, such as a side length, is multiplied by the scale factor of a dilatation. A dilation is a transformation where all line segments' lengths are altered uniformly. While a dilatation can alter a figure's size, it cannot alter a figure's form. Dilations are not isometries as the figure's size changes.

For what values of x, does the graph's slope equal zero?

Nutka1998 [239]

Answer:

1 < x ≤ 2

Step-by-step explanation:

A graph's slope equals zero when there is a change in the x-value, but there's no change in the y-value.

Here, we can see in the piecewise function that between 1 (not included) and 2 (included), the slope of the graph is 0.

Therefore, 1 < x ≤ 2 is correct
