ANSWER

The multiplication, CA is defined, and its dimension is 3×2

EXPLANATION

Matrix A is a 2x3 matrix.

Matrix C is a 3×2 matrix.

The product of the two matrices , CA, is defined if and only if the inner product of their dimension are the same.

CA = (2 \times 3)(3 \times 2)

The inner products are the same.

Hence the matrix multiplication, CA is defined and its dimension is the outer products.

2 \times 2

balu736 [363]

Answer:

  • No, no, yes, yes

Step-by-step explanation:

–10.5 < 3a ⇒ -3.5 < a ⇒ a > -3.5

  • <u>no</u> as variable has positive coefficient

b/6 ≤ 7 ⇒ b ≤ 42

  • <u>no</u> as variable has positive coefficient

–4.5c > 9 ⇒ c < - 2

  • <u>yes </u>as variable has negative coefficient

–21/5 ≤ –5/2d ⇒ (-21/5)*(-2/5) ≥ d ⇒ d ≤ 42/25

  • <u>yes</u> as variable has negative coefficient
