Joseph pays $20 for his base phone plan in addition to the $0.23 per text. micki pays $10 for her phne plan plus $0.15 per text. what is the function for joesphs phone plan and for mikis phoen plan?

Not really Specific in asking in what way you want it answered... So here is what Im able to understand.

Function

Joseph : 20 + .23x = y

Micki : 10 + .15x =y

Hope this is what your asking...

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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
