Write in 0 and 0 at the top:  this indicates that if there are zero pennies, the height of the tower is 0.  This is the point (0,0).  Another point is (4, 28):  a tower of 28 pennies is 4 cm tall.

Find the slope of the line connecting (0,0) and (4,28).
            4cm - 0 cm
    m = ----------------- = (1/7) (cm/penny)
            28 - 0

The equation we need, relating # of pennies to height of tower, is 

       t = (1/7) (cm/penny)x, where x is the # of pennies.

Thus, if x = 1, then t=1/7 cm

And, if x =15, then t = 15/7 cm

And so on.

Which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negati
Nat2105 [25]

The simplest form of the algebraic expression is x^-4y^-8/x^12y^-12 (Option B)

<h3>What is simplification?</h3>

The term simplification is mathematics refers to the depiction of the expression in its lowest possible format. In the simplest form, the expression can not be simplified further.

Now we have the original expression as;

(xy^2/x^-3y^3)

The only possible step in the expansion is to open up the bracket by the laws of indices and we get;

x^-4y^-8/x^12y^-12 (Option B)
