Identify the property that justifies each step asked about in the answer area below.
Line 1:
19+ 8x)
Line 2:
1(8x +9)
Line 3:
8x + 9

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

hello,

as   long as they add up to 180 its correct.
