Volunteer drivers are needed to bring 80 students to the championship baseball game. drivers either have cars, which can seat 4 students, or vans, which can seat 6 students. the equation 4c + 6 = 80 describes the relationship between the number of cars c and number of vansv that can transport exactly 80 students. explain how you know that this graph represents this equation.

answer:

because the y-axis shows the vans so the y-intercept shows if there was only vans, they would need 13.   same with the cars which is the x-axis.   if there was no vans then there would have to be 20 cars.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
