THIS IS PRETTY EASY IM JUST d u mb SO PLEASE HELP: The elimination method was used to solve the following system of equations:

x2 – y = –4
x2 + y2 = 16

Which of the following is the correct y-coordinate of the solution?
ITS EITHER 4, 0, -3 OR -5

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
