Note that r sin theta always equals "x" in polar coordinates.

Thus, x = -2. That's the graph in the upper, right-hand corner.

Juan is making t-shirts to sell at a concert.

o-na [289]

Answer:

7 shirts

Step-by-step explanation:

The function for producing shirts is

f($) = 50 + 7.5(x), where x is the number of shirt

The function for selling shirts is

f($) = 15(x)

For there to be a profit, he must make more money selling the shirts than he spent on making the shirts

Therefore, 15(x) > 50 + 7.5(x)

15x > 50 + 7.5x

15x - 7.5x > 50

7.5x > 50

x > 6.67 shirts

To make a profit, Juan must sell at least 7 shirts

Aleonysh [2.5K]

Answer: D) 10 jerseys

Step-by-step explanation:

Let j represent the number of jerseys and C for total cost

Local company eqn: C = 5.25j + 45

Online company eqn: C = 7.75j + 20

Set both sides equal to solve:

5.25j + 45 = 7.75j + 20

5.25j - 7.75j = 20 -45

- 2.5j = -25

$\frac{-2.5j}{-2.5}=\frac{-25}{-2.5}$

j = 10

Therefore, the cost is the same for both companies when 10 jerseys are sold
