Answer:

Step-by-step explanation:

$Original \: price = 600000GH Cedis\\New \: price =450000gh cedis\\\\Difference \:between \:the \:two \:values(discount) =\\ 600000-450000=150000\\\\Discount \: percentage = \frac{Discount}{Original price} \times 100\\\\ = \frac{150000}{600000} \times 100\\\\= \frac{1}{4} \times 100\\\\= \frac{100}{4} \\\\= 25 \%$

Determine whether each ordered pair is a solution to the inequality x+y<−1.

polet [3.4K]

Answer:

Choice A. (10, -1)
Choice B. (-8, 9)
Choice D. (6, -3)

Step-by-step explanation:

If we plug the coordinates of point A into the inequality, then we get,
x+y > -2

10 + (-1) > -2
9 > -2
That last inequality is a true statement since 9 is to the right of -2 on the number line. That means (10,-1) is a solution. Choice A is one of the answers.
Choices B and D are also answers for similar reasons.
Something like choice C is not a solution because
x+y > -2
-1+(-9) > -2
-10 > -2
Which is false.
You should find that choice E is false as well.

If you graphed the inequality and all of the points mentioned (see below), then you can visually confirm the answers. Notice how points A, B and D are in the blue shaded region which is the solution set.
The point E on the boundary does not count as a solution. This is due to the lack of "or equal to" portion of the inequality sign. That visually shows point E is not a solution. Point C isn't a solution either as it's nowhere near the blue shaded region.
