What is 5x+4y=-14, 3x+6y=6 in matrix

is the required matrix form.

Step-by-step explanation:

Here, the given system of equation is:

5 x + 4 y = -14,

3 x + 6 y = 6

In a system of equation, the matrix for is given as

AX = b

Here, A  = Co-efficient Matrix, X =  Variable Matrix and B = Constant Matrix

Considering the given system:

Co-efficient Matrix(A)  =

Variable Matrix(X) =

Constant Matrix(b)   =

Hence, the combined matrix form  of AX = b is

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
