Using a system of equations, it is found that the value of “b” in ax^2 + bx + c would be of:

B. 6

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, when x = 0, y = 15, hence c = 15.

When x = -1, y = 10, hence:

a - b + 15 = 10

a - b = -5

a = b - 5.

Then, when x = 1, y = 22, hence:

a + b + 15 = 22

a + b = 7

b - 5 + b = 7

2b = 12

b = 6.

Hence option b is correct.

A store has clearance items that have been marked down by 60% they having a sale, advertising an additional 30% off clearance it
bagirrra123 [75]

The original price is 100% of the price. If the price is marked 60% off, then you pay 40% of the original price.

An item costs x dollars.

With the 60% off discount, it now costs 40% of x, or 0.4x.

Now you apply a 30% discount.

For the second discount, consider the price 0.4x to be the new original price. If the price is now discounted 30%, you will pay 70% of the new original price.

Start with 0.4x.

Now calculate 70% of 0.4x.

70% of 0.4x = 0.70 * 0.4x = 0.28x

After applying the 60% discount and the 30% discount, the item that originally cost x now costs 0.28x. 0.28x is the same as 28% of x. The amount you pay is 28% of the original price.

Answer: 28%
