There are 23 textbooks on the shelf in ms. mcdonald's class. each cover is 13 inches long and 5 inches wide ? what is the combined area of all the textbooks?

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
