Answer:
This mapping isn't a function.
Step-by-step explanation:
A mapping specifies a relation between two sets of items (input and output). For example, a mapping of the form would map the input to output and map the input to output .
A function is a mapping where each input is associated with exactly one output.
Note that both and are in the mapping given in this question. The input is mapped to more than one outputs. Thus, this mapping isn't a function.

Answer:
150
Step-by-step explanation:
the total angle of a flat line is 180
since one side is 30 180-30 is 150
For number 1, you would have to subtract five on both sides to get 3x is greater than or equal to 15, then you would have to make the variable (x) on its own. So, you would divide 3x by three and 15 by three to get x=5.
I am not sure if you want me to do number two, but i will do it anyways, so 8(x+4) =-8, first you would have to multiply the eight into the parenthesis, so it would be 8x +32+-8 and then you would subtract 32 on both sides to get 8x=-40 you then divide -40 by 8 and you get x is greater than -5
