A circle has a center at C(7, 2). If point A(13, 12) lies on the circle, which of the following is the slope of the tangent line to circle C at point A? 1) 5/3
2) -5/3
3) -3/5
4) 3/5

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

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'.

i believe that the answer is

b. y-1=-2(x-4)

hope this !

idk what the heck he answer is, i’m just putting this here so i finish my account
