Xavier has $23.50 in his savings account. he deposits $35 every week. his mother also deposits $20 into the account every time xavier washes the car. his savings account balance can be shown with the following expression: 20c + 35w + 23.50 part a: identify a coefficient, a variable, and a constant in this expression. (3 points) part b: if xavier saves for 12 weeks and washes the car 3 times, how much will he have in his account? show your work to receive full credit. (4 points) part c: if xavier’s mother deposited $25 after each car wash, would the coefficient, variable, or constant in the expression change?

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'.

i got 10.28 but that rounds up to 10.3
