The sytem has no solution if inequality does not share a common area. The inequality -12x + 3y > 9 consist the region to left of line -12x + 3y = 9. So for no solution the region to left of equation -12x + 3y = 9 is suitable.

Thus inequality for no solution is, -12x + 3y < 9.

PART B:

For infinite solution the region of both inequality must overlap each other, or the inequality is same with some multiplication of divison factor. So inequality for infinite many solutions is,

$\begin{gathered} (-12x+3y>9)\times-1 \\ 12x-3y$

Thus inequality for infinite many solution is 12x - 3y < -9.

Jordan would like to buy an oil painting with an original price of $744.00. Which coupon should he use 55% off or $400.00

Ksivusya [100]

Answer:

The 400 coupon is 80 cents better

Step-by-step explanation:

First find the sale price with the coupon

744 - 400 = 344

Now find the sale price with the discount

100-55 = 45

We will pay 45% of the original price

744*45%

744*.45

344.80
