Answer:
Infinitely many solutions
Step-by-step explanation:
6x + 10 = 2(3x + 5)
Distribute;
6x + 10 = 6x + 10
Infinitely many solutions
20 x 20 = 400
4(1/2 x 20 x 30) = 1200
400 + 1200 = 1600
So, D
Answer:
We have to choose any one from option B and option C
Step-by-step explanation:
We have to perform a subtraction of two decimal numbers.
(9.43 - 4.286) = (9.430 - 4.286) = 5.144.
Hence, the answer is 5.144 which is given both options B and C.
In case there are two options with the same value and the value is the answer, then you choose any one of them but not both.
Here in our case, we have to choose any one from option B and option C and we will be rewarded full marks. (Answer)
Answer:
Step-by-step explanation:
An eigenvalue of n × n is a function of a scalar 
considering that there is a solution (i.e. nontrivial) to an eigenvector x of Ax =
Suppose the matrix ![A = \left[\begin{array}{cc}-1&-1\\2&1\\ \end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1%26-1%5C%5C2%261%5C%5C%20%5Cend%7Barray%7D%5Cright%5D)
Thus, the equation of the determinant (A - 1) = 0
This implies that:
![\left[\begin{array}{cc}-1-\lambda &-1\\2&1- \lambda\\ \end{array}\right] =0](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1-%5Clambda%20%26-1%5C%5C2%261-%20%5Clambda%5C%5C%20%5Cend%7Barray%7D%5Cright%5D%20%3D0)
Hence, the eigenvalues of the equation are 
Also, the eigenvalues can be said to be complex numbers.
