Answer:
The profit function would be p(x) = 7x - 20
Step-by-step explanation:
In order to find this, start by listing just as asked.
p(x) = r(x) - c(x)
Now input the functions where indicated
p(x) = 12x - (5x + 20)
p(x) = 12x - 5x - 20
p(x) = 7x - 20
Answer:
640,121
Step-by-step explanation:
A because if you multiply 50,000 by .10 (10%) you'll get 5,000
No, it is not. Using the distributive property, multiply 2 to 3x and -5 to get 6x-10. 6x-8 does not equal 6x-10, they have the same coefficient by not the same constant.
The inequality -y<3x-5 by multiplying by -1 becomes y>-3x+5.
1. Draw line y=-3x+5. When x=0, y=5, when y=0, -3x+5=0, x=5/3.
2. Choose the correct semiplane, substituting (0,0) into the inequality. Since 0 is not greater than 5, you can conclude that point (0,0) isn't a solution and doesn't belong to the shaded area.
3. The correct answer is first choice
