Abaseball player's batting average is found by dividing the number of hits the player has by the number of at-bats the player has. suppose a baseball player has 45 hits and 130 at-bats. write and solve an equation to model the number of consecutive hits the player needs in order to raise his batting average to 0.400. explain how you found your answer.

12 hits

Step-by-step explanation:

Let x be the number of hits needed

1 hit equals an at-bat.

(45+x)hits / (130+x)at-bats = 0.4

(45+x) = 0.4(130+x)

45 + x = 52 + 0.4x

45 - 52 = 0.4x - x

-7 = -0.6x

x = -7/-0.6

x = 11.667

x = 12(approximately)

12 hits are necessary since there are no fraction of hits

answer: 48

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'.
