Alex rented a booth at the comic pro conference to sell his new graphic novel. the booth rental is $50, and the cost to produce each book is 5.25 each. the novel sells for 12.95 each. write am inequality to represent the number of graphic novels he must sell to make a profit.

12.95x > 5.25x + 50

Step-by-step explanation:

Let x = number of books he sells.

total cost = cost of books + fixed cost

total cost = 5.25x + 50

income = 12.95x

To make a profit, the income from sales of books must be greater than the total cost.

12.95x > 5.25x + 50

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
