Answer: the graph is not shown, but I'll try to explain how hypothetically, you would be able to graph g(10). If you are given something like an image of the graph, find slope and y-intercept first. The y-intercept is the point (0, #), and is on the y-axis. After finding what g(x) = mx + b <- slope intercept form is, substitute 10 for x, then solve.

Answer: average speed is 8 km/h
Step-by-step explanation: in upstream his speed is 9 km/h -3km/h.
So his speed is 6km/h and he needs time t= s/v= 1.5 km: 6 km/h = 0.25 h
Downstream his speed is 9 km/ + 3km/h = 12km/h and time is
1.5 km:12km/h= 1/8 hours= 0.125 h
Average speed v = s/t = 3km: (0.25 + 0.125 ) h = 8 km/h
Answer:
x^2 + 18x + 81 complete's the square.
Step-by-step explanation:
y = [x^2 + 18x + (18/2)^2 ] - (18/2)^2
y = [x^2 + 18x + 81] - 81
y = (x + 9)^2 - 81 This is just to make the completion of the square accurate.
You can't just add something to an expression. You have to balance it out.
