Answer:
x= -19
Step-by-step explanation:
5x-10 = 7x +28
2x=-38
-38÷2
×= -19
<u>finding domain: </u>
to find the domain, we are finding all of the x values.
<u>example: </u>
say we have the points: (2,5) (4,8) (1,7) (8,10) (13,2)
the domain would be a list of all of the x values of all of the coordinate points. therefore the domain would be:
<u>domain: </u>
{1,2,4,8,13}
<u>conclusion:</u>
since you have not attached the function or a graph, you will have to find the domain on your own (unless you attach one now). hope this helps!
