Cada perro de la raza B consume cada semana 3Kg de alimento tipo I, 4 Kg del II y 5Kg del III. Para la raza C consume cada semana 2Kg del I, 1Kg del II y 5Kg del III. Cada semana se proporcionan 2500Kg de alimento tipo I, 2000Kg del II y 5500 del III. El número de perros de cada especie se pueden alimentar son?

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
