Tell whether each table represents a proportional relationship. If it does, identify the constant of proportionality

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

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)
