Help me with 8 - 11 please

(question8 x=28),(question9 x=18),(question10 x=22),(question11 x=45)

Step-by-step explanation:

Question 8

2x+1+33=90

2x+34=90

2x=90-34

2x=56

Divide both sides by 2

x=56/2

x=28

Question 9

3x+11+25+90=180

3x+126=180

3x=180-126

3x=54

Divide both sides by 3

x=54 ➗ 3

x=18

Question 10

5x+12=6x-10

Collect like terms

6x-5x=12+10

x=22

Question 11

45+3x=180

3x=180-45

3x=135

Divide both sides by 3

x=135 ➗ 3

x=45

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'.

idk
