Matrices Exe- 9A Concise Class-10 ICSE Maths Selina Solution Ch-9
Que-1: State, whether the following statements are true or false. If false, give a reason.
(i) If A and B are two matrices of orders 3 2 and 2 3 respectively; then their sum A + B is possible.
(ii) The matrices and are conformable for subtraction.
(iii) Transpose of a 2 1 matrix is a 2 1 matrix.
(iv) Transpose of a square matrix is a square matrix.
(v) A column matrix has many columns and one row.
Ans:
(i) False
The sum A + B is possible when the order of both the matrices A and B are same.
(ii) True
(iii) False
Transpose of a 2 1 matrix is a 1 2 matrix.
(iv) True
(v) False
A column matrix has only one column and many rows.
Que-2: Given: ,………… find x, y and z.
Ans: If two matrices are equal, then their corresponding elements are also equal. Therefore, we have:
x = 3,
y + 2 = 1 y = -1
z – 1 = 2 z = 3
Que-3: Solve for a, b and c if ……
Ans: If two matrices are equal, then their corresponding elements are also equal.
(i)
a + 5 = 2 a = -3
-4 = b + 4 b = -8
2 = c – 1 c = 3
(ii) a= 3
a – b = -1
b = a + 1 = 4
b + c = 2
c = 2 – b = 2 – 4 = -2
Que-4: If A = and B = ; find: (i) A + B (ii) B – A
Ans:
Que-5: If A=…….., B = ………and C =…….; find:
(i) B + C (ii) A – C (iii) A + B – C (iv) A – B +C
Ans:
Que-6: Wherever possible, write each of the following as a single matrix ……
Ans:
Que-7: Find, x and y from the following equations :……………..
Ans:
Que-8: Given: M =…………. , find its transpose matrix Mt. If possible, find: (i) M + Mt (ii) Mt – M
Ans:
Que-9: Write the additive inverse of matrices A, B and C: Where ……
Ans:
Que-10: Given ……………………; find the matrix X in each of the following:
(i) X + B = C – A
(ii) A – X = B + C
Ans:
Que-11: Given ………………; find the matrix X in each of the following:
(i) A + X = B
(ii) A – X = B
(iii) X – B = A
