If c(m)= 0.50m+30 represents the cost of renting a car, how many miles were driven if the cost is $130?

200 miles is the answer.

Step-by-step explanation:

Given relation is : C(m)= 0.50m+30

C(M) = Cost for renting a car

0.50m = Cost per mile driven

30 = Initial cost

M = Miles driven

Now putting 130 in place of c(m)

Therefore, if the cost is $130, then 200 miles were driven.

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'.

b. f(x) = –√x + 3this is the correct answer
