Give the interval that describes the set of values shown above
The interval marked in blue has the following features:
* Starts with a filled blue dot at x=2
* Ends with a filled blued dot at x=4
* Runs from x=2 to x=4 with a blue line
The filled dots indicate that the endpoints are included in the interval
The line indicates that all the values in between the interval are included in the interval
There are two basic forms to indicate an interval with included endpoints:
* A pair of values (the endpoints) comma-separated included in a pair of brackets:
Interval: [2,4]
* The closed interval indicated by inequalities signs:
-85/12 _
or in decimal form its 7.08333333
or mixed number form 7 1/12
Solution:
we are given that
Clayton needs to reflect the triangle below across the line y=x.
And as we know the reflection of the point (x,y) across the line y = x is the point (y, x).
Hence the new Traingle will be on the other side of the line y=x and position of x and y-coordinates of the vertices of the trangle gets interchanged.
Hence the Options that applies are:
C’ will move because all points move in a reflection.
The image and the pre-image will be congruent triangles. (Because reflection just changes the position of the trinagle not the property)
The image and pre-image will not have the same orientation because reflections flip figures.
