{[9+3) divided by 2] - 2} times [3 times (14 - 5)] =

Step-by-step explanation:

Use PEDMAS

First the inner parenthesis

i) (9+3) & (14-5)

ii) [12 ÷ 2] & [3*9]

iii) {6- 2}

{[(9 + 3) ÷ 2] - 2} * [3*(14 - 5)]={[12 ÷ 2] - 2} * [3*9]

                                            = {6-2}* [27]

                                             = 4 * 27

                                             = 108

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

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'.
