Mrs. Thomas is calculating how long it will take for her to drive to her sister's house. Her sister lives 700 miles away, and she will drive at a constant speed of 55 miles per hour. She writes the equation y=700 - 55x where y is the number of miles left to drive after x hours. Which of the following answer choices best describes Mrs. Thomas's equation?

A. Mrs. Thomas's equation is correct

B. Mr. Thomas's equation is incorrect because she switched the variables. The correct equation is x = 700y + 55

C. Mrs. Thomas's equation is incorrect because she used subtraction instead of addition. The correct equation is y = 700+ 55x

D. Mr. Thomas's equation is incorrect because she paired the variable
the wrong number. The correct equation is y = 700x - 55

?

Step-by-step explanation:

congruent segments

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'.
