Solve 12x-19=5x+9please show working​

4

Explanation:

your goal is to isolate the x. to do this, youd subtract 5x from both sides

7x-19=9

keep in mind you want to isolate the x. now you want to ADD the 19 to both sides because its a negative number. you want to get it to 0.

7x=28

now this is a one step equation. you just need to divide 28/7 and youll get 4

i hope this helped, let me know if it doesnt!

satin. 

"very shiny satin may look great in the fabric store or in the sewing room, but once onstage it can look fake and cheap as it reflects the light from the fixtures."

coordinates of r(b,c)

slope of nm is 0.

step-by-step explanation:

the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

the midpoint of the line segment nk is given by

∴r(b,c)

the slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

slope of rs is

hence

coordinates of r(b,c)

and slope of nm is 0.
