There is a two-digit number whose units digit is six less than the tens digit. four times the tens digit plus five times the units digit equal 51. find the digits.

T = U + 6
4T + 5U = 51 substitute for T
4(U + 6) + 5U = 51
4U + 24  + 5U = 51
9U + 24 = 51
9U = 27
U = 3

t = U + 6
t = 3 + 6
t = 9

Check
4*t + 5*u = ? 51
4*9 + 5*3 = ? 51
36 + 15 =? 51
51 = 51 It checks.

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
