Esmerelda and brittany are at the library working on their algebra homework. esmerelda is 79 done with her homework, and brittany is 3136 done with the same work. they want to compare these fractions to know who is closer to being done, but they know they cannot compare the fractions until they have the same denominator. what are these two fractions rewritten with a common denominator?

select one:
a. 79 and 89
b. 2836 and 3136
c. 1118 and 1518
d. 736 and 3136

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
