7+ (x + 2y)i = x + 3i where x and y are real numbers

7 + (x + 2y)i = x + 3i

Equating the real and imaginary parts of the expression.

7 = x                     x + 2y = 3

                             7 + 2y = 3

                             2y = 3 - 7

                             2y = - 4

                              y = 

                              y = -2

Hence, x is 7 and y is -2.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
