Slope of KL = 2/2 = 1.
Slope of MN = 2/2 = 1.
Slope of LM = -1/2.
Slope of NK = -1/2.
The slopes of opposite sides KL and MN are equal.
The slopes of opposite sides LM and NK are equal.
Since quadrilateral KLMN has two pairs of opposite sides that are parallel, it is a parallelogram.
Step-by-step explanation:
Hello, let's note A the matrix, we need to find such that A= I, where I is the identity matrix, so the determinant is 0, giving us the characteristic equation as
We just need to solve this equation using the discriminant.
And then the eigenvalues are.
To find the basis, we have to solve the system of equations.
Thank you
Answer:
$750
Step-by-step explanation:
We can set up the equation 30x + 50y = z where x = the amount of small dogs, y = the amount of big dogs, and z = the total.
After plugging in the x and y values to solve for z, we are left with the following equation:
30(15) + 50(6) = 750
Answer:
28,000 + (n -1)800.
Step-by-step explanation:
The first term is 28,000 and the common difference = 28,800 - 28,000 = 800 .
Each year 800 is added to the salary.
