There is a proportional relationship between minutes and dollars per minute, shown on a graph of printing expenses. The graph passes through the point (1,4.55). What is the slope of the graph? What is
the unit rate? Complete the explanation.
The slope is
The unit rate is $ min. If the graph of a proportional relationship
passes through the point
r), then r equals the slope and unit rate.

The length of what is left would be 1 1/2 feet long.

Magic man is here, but unfortunately he is broke won’t you him out

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
