Eghh i'm so bad at algebra > .< ? the length of a rectangle is 9.7 cm more than 4 times the width. if the perimeter of the rectangle is 91.4 cm, what are its dimensions?

or with this one? a rental car agency charges a flat fee of $110.00 plus $46.00 per day to rent a certain car. another agency charges a fee of $70.00 plus $54.00 per day to rent the same car.
using a graphing calculator, find the number of days for which the costs are the same. round your answer to the nearest whole day.

step-by-step explanation:

for the friend request.

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'.
