Answer:

the answer is 50

Step-by-step explanation:

first you plug in the x and y in the equation, making it 6(7)=-4(-2)           then, you multiply the numbers together, making the equation 42+8.                                                    finally, you add those numbers together, giving you the answer 50

It's 50. Just multiply 6 times 7 and you get 42. Then you multiply 4 times -2 which is -8 . Then you subtract the products and you get 50. Your welcome.

A yacht that travels 1.375 km in 165 minutes expressed in km/h
Tomtit [17]

The speed of a yacht traveling a distance of 1.357 km in 165 minutes is 0.5 km/h

<h3>What is Speed?</h3>

The speed of an object is the distance covered by the object in respect to time.

Mathematically:

\mathbf{Speed = \dfrac{distance}{time}}

\mathbf{Speed = \dfrac{1.375 \ km}{165 minutes }}

  • We know that 60 minutes = 1 hour
  • 165 minutes = 2.75 hours

\mathbf{Speed = \dfrac{1.375 \ km}{2.75 \ hours}}

Speed = 0.5 km/hour

If D is an n × n diagonal matrix with entries dii, then det D = d11d22 ∙ ∙ ∙ dnn. Verify this theorem for 2 × 2 matrices.
nadya68 [22]

Answer:

Verified

Step-by-step explanation:

Let the diagonal matrix D with size 2x2 be in the form of

\left[\begin{array}{cc}a&0\\0&d\end{array}\right]

Then the determinant of matrix D would be

det(D) = a*d - 0*0 = ad

This is the product of the matrix's diagonal numbers

So the theorem is true for 2x2 matrices
