Answer:

NO SOLUTION

Step-by-step explanation:

Let's actually solve the system

x-4y=1

5x-20y=4

Let's eliminate y.  To do this, multiply the first equation by -5, obtaining

-5x + 20y = -5

Now add this result to the second equation:

-5x + 20y = -5

5x -  20y =  4

--------------------

           0   = -1

This result is never true.  Thus, this system of linear equations has NO SOLUTION.

Hello!

Let's subtract the eight DVDs Joe received as gifts, because he didn't buy them on his own.

35 - 8 = 27

Now, divide the remaining CDs by the 3 years he collected his DVDs in.

27 ÷ 3 = 9

Joe bought 9 DVDs last year.

PLEASE HELP. For a field trip, a bus company charges a flat fee plus an additional fee per student. For 30 students, the total
bogdanovich [222]

Step-by-step explanation:

the change in cost of 145-135.50 = 9.50 for an increase of students from 25 to 30. The ratio of change of cost to change of students = 9.50/5 = 1.9 and becomes the slope coefficient "m" in the formula y= mx + b. y = the total cost, mx becomes the variable cost and b becomes the fixed cost. To find b, use the data point given where the total cost = $135.50 when the students = 25, or 135.50 = 1.9*25 +b. Solving for b yields $ 88. Note that the other data point is where the total cost is $145 for students = 30. Using the new total cost equation shows that 30*1.9+88= 145
