Answer:

B) -5x + 2y + 1 > 0

Step-by-step explanation:

Given point is (-2,-1)

to find out which inequality satisfies this point we plug in x and y value of the given point in each inequality

A) 5x - 2y + 1 > 0

x=-2 and y=-1

5(-2) - 2(-1) + 1 > 0

-10+2+1>0

-7>0 is False

B) -5x + 2y + 1 > 0

-5(-2) +2(-1) + 1 > 0

10-2+1>0

9>0 is True

C) -2x + 5y - 1 > 0

-2(-2) +5(-1) -1 > 0

4-5-1>0

-2>0 is False

D) 2x + 5y - 1 > 0

2(-2) +5(-1) - 1 > 0

-4-5-1>0

-10>0 is False

An electric guitar is on sale at 40% off. if the sale price is 179.94 ,what is the original.
n200080 [17]
Let x = original price
Knowing that multiplying the original price and the discount is the discount price. We formulate:
x(1 - 0.40) = 179.94
x(0.60) = 179.94
x = 179.94/0.60
x = 299.9
That is about 300 of the original price.
