<em>x</em> ² - 4<em>x</em> + <em>y</em> ² + 8<em>y</em> = -4
(<em>x</em> ² - 4<em>x</em> + 4) + (<em>y</em> ² + 8<em>y</em> + 16) = -4 + 4 + 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 4²
which is the equation of a circle centered at (2, -4) and with radius 4.
The answer is -2/5; hope this helps
Answer:
D
Step-by-step explanation:
Since it’s asking for numbers between -1 and 8 the equation cannot contain a equal symbol therefore it must be D
1050 × 100 ÷ 30 would be what you plug into a calculator (if you have one) to get the answer.
100% = 3500.
Answer:
Step-by-step explanation:
Equation to remember:
where t = time
= 1200 since that's the initial population
= .35 rate of change \\
= 5 years
Plug in the numbers;
Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.
