solve this system of linear equations. separate x- and y- values with a comma. 7x=-67-11y 5x=-73-11y

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h

Since we have computer algebra systems that can solve polynomial division problems for us, why is it necessary to learn how to do these things by hand?
