What is 0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2) simplified?

1.55x - 2.16

Step-by-step explanation:

To simplify the expression, we expand the brackets while taking note of the signs:

0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2)

(0.2 * 5x) + (0.2 * -0.3) + (-0.5 * -1.1x) + (-0.5 * 4.2)

x - 0.06 + 0.55x - 2.1

Collect like terms:

x + 0.55x - 0.06 - 2.1

=> 1.55x - 2.16

This is the simplified expression.

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'.
