Answer:

B (1/2,-2)

Step-by-step explanation:

4b + 13c = -24 --(1)

12b - 5c = 16 --(2)

(1)x3

12b + 39c = -72 --(3)

(3)-(2)

12b + 39c - 12b + 5c = -72-16

c = -2

Sub c = -2 into (1)

4b = -24 - 13(-2)

b = 1/2

Use determinants to find the area of the parallelogram shown below

r-ruslan [8.4K]

Answer:

Step-by-step explanation:

To find the determinant of a parallelogram given points (a, b), (c, d), and (e, f), we can use

$\left[\begin{array}{ccc}a&b&1\\c&d&1\\e&f&1\end{array}\right]$ and calculate the determinant of that. Three points on the parallelogram are (-1,1), (-1, -5), and (4, 5). Plugging these into the matrix, we get

$\left[\begin{array}{ccc}-1&1&1\\-1&-5&1\\4&5&1\end{array}\right]$ . The determinant is equal to

$-1 *det \left[\begin{array}{ccc}-5&1\\5&1\end{array}\right] \\- 1 * det \left[\begin{array}{ccc}-1&1\\4&1\end{array}\right] \\\\+ 1 * det \left[\begin{array}{ccc}-1&-5\\4&5\end{array}\right] \\= -1 * (-5*1 - (1*5))- 1 * (-1 * 1 - (4*1)) + 1 * (-1 * 5 - (-5*4)) \\= -1 *(-5-5) -1 * (-1 - 4) + 1 * (-5 - (-20))\\= -1 * (-10) -1 * (-5) +1 * (15)\\= 10 + 5 + 15\\=30$
