1) steven works at a large home appliance store. he earns a base salary of $20,000 plus commission which can be modeled by the equation y = 0.1x + 20,000. what is the meaning of the y-intercept in the equation?

Steven's base pay.

Step-by-step explanation:

x = 0 for the y-intercept.

y = 0.1x + 20,000

y = 0.1(0) + 20,000

y = 20,000

The y-intercept represents Steven's base pay.

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
