EXTRA CREDIT: Briggs is downloading movies and songs. Each movie costs $5 and each song costs $1. Briggs' mom said he can have at most 10 downloads and he can spend at most $15. Write a system of linear inequalities. Let x represent the number of movies Briggs can download and y represent the number of songs he can download. Graph the inequalities. Do not scale your graph

answer:

what is your question that you ask

step-by-step explanation:

i think 5 miles per hour

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
