Achain saw rental for $12 a day. a sharpening fee of $5 is charged for each rental. write an equation for the number of dollars (y) that must be paid to rent a chain for x days. how many days can one rent a chain saw for a cost of $125?

y= 12x+5 and It would be 10 days.

Step-by-step explanation:

Y= total

+5 = each rental

X= # of days

125= 12x+5; x=10

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'.
