Considering these two equations: y - 2x = 25
19y + 10x = 25
Which expression can be substituted for y
in the bottom equation of the system to
solve the system by substitution?

The first one can be substituted for y, when you add 2x to both sides. At the end you’ll have y = 2x + 25 which can be substituted in the second equation for y.

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
