Answer:
factoring trinomial
Step-by-step explanation:
x^2 - 6x - 27 = 0
(x - 9)(x + 3)
x = ( 9 , - 3)
First, you find 5% of $50.
To do this, you times 50 by 0.05. This is because if you were to turn 5% into a decimal, with 1.0 being 100%, 5% would become 0.05.
50 x 0.05 = 2.5
After you have the amount, simply add it onto the original $50.
50 + 2.5 = 52.5
The new price is $52.5.
Answer:
x < -3 but not including -3/open circle at -3
Step-by-step explanation:
<u>Step 1: Add 3 to both sides</u>
2x - 3 + 3 < -9 + 3
<em>2x < -6</em>
<em />
<u>Step 2: Divide both sides by 2</u>
2x / 2 < -6 / 2
<em>x < -3</em>
<em />
Answer: x < -3 but not including -3/open circle at -3

Step-by-step explanation:
When you expand a number to show the value of each digit, you're writing that number in expanded form. Writing numbers in expanded form just means that you're showing the value of each digit in the number. With the exception of zeroes, the larger the number, the longer its expanded form will be.
