The difference of three times a number and 5 is equal to 79.
I'm not sure how to explain this one... it's just a verbal sentence. Hope this helps!
Answer: -1 ± <em>i</em>√35
⁻⁻⁻⁻⁻⁻⁻⁻
6
Step-by-step explanation:
From the quadratic equation,
X = -b ±√b² - 4ac
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2a
From the given equation, -3x² - x - 3 = 0
where a = -3, b = -1, c = -3
Now substitute for the values in the formula above
x = -(-1) ± √(-1)² - 4(-3)(-3)
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2(-3)
x = 1 ± √ 1 - 36
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = 1 ± √ -35
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = -1 ± <em>i√35 this is because it has a negative root.</em>
<em> ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻</em>
<em> 6</em>
<em> The answer is b</em>
Options a, b, and d are all correct.
I just substituted the x values into a calculator and checked if the y value was equal as well
Answer:
c. 
Step-by-step explanation:
When plugging in zero into the given equation:
Answer is in indeterminate form = use L'Hospital's Rule:
(Derivative of the top / Derivative of the bottom)
Rearranged equation:
Plug zero back into equation:
Answer:
Answer: 12
Step-by-step explanation:
One yard is three feet. So three times four is 12 because it makes four yards in total with each side being a yard.
