Translate each of the following word phrases into algebraic expressions using the symbols given. Eg) Twelve times a number 'x', plus a second number 'y'

= 12x + y

1) Half the product of two numbers x and y, minus five times a third number z.

half that's 1/2

product that's multiplication ×

therefore (x*y)/2- 5z

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

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
