Which expressions are equivalent to -56z+28

-28(2z-1)

Step-by-step explanation:

Here what you do is factor out the GCF(greatest common factor), which is 28 and then put the rest of the equation: 2z-1 in parenthesis and multiply to check, which makes your equation the same as -56z+28.  I hope this helps.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
