Well after graphing the function. The domain and range would be all real numbers as there are no restrictions and the graph will keep on increasing for the X and y values.
Answer:
13=x
Step-by-step explanation:
Side-spliting theorem
21/(x-4)=14/6
cross multiply
21*6=14*(x-4)
distribute 14
126=14x-56
add 56 to both sides
126+56=14x-56+56
leaving you with
182=14x
Divide both sides by 14 to get x by itself
182/14=14x/14
13=x
40/40
8x5=40
10x4=40
