Let a=
3 2
−1 5
3 −4
and x be a 3 × 2 matrix. if a+ x =
−2 3
4 1
1 −5
then find x

X =

Step-by-step explanation:

given,

A + X = Q

X = A - Q

A =

Q =  

now

X =  

X =

X =

hence, the required matrix is given above

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
