The Jacobian has determinant
Answer:
A. 2 distinct roots.
Step-by-step explanation:
2x^2 + 8x + 3 = 0
Finding the discriminant:
b^2 - 4ac = 8^2 - 4 * 2 * 3
= 64 - 24
= 40
The discriminant is positive but not a perfect square
So there are 2 distinct ,real, irrational roots.
Slope=(y2-y1)/(x2-x1)= (3−3)÷(2−10)=0
<em>n = - 1</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>6 = - 2(10n + 7)</em>
<em>6 = - 20n - 14</em>
<em>20n = - 6 - 14</em>
<em>20n = - 20</em>
<em>n = - 20 : 20</em>
<em>n = - 1</em>
<em />
<em>6 = - 2(10×-1 + 7)</em>
<em>6 = - 2(-10 + 7)</em>
<em>6 = - 2(-3)</em>
<em>6 = 6 (true)</em>
<em>Good luck !</em>
