To find one intercept, set d = 0 in the equation and solve for q. For the other intercept, set q = 0 and solve for d. These intercepts indicate that the piggy bank could contain either 54 quarters without any dimes, or 135 dimes in the absence of quarters.
5q + 2d = 270 To determine the intercepts, start by setting d to 0, then to find q. The conditions yield: 5q = 270 q = 54; (0, 54) 2d = 270 d = 135; (135, 0) This equation illustrates the total number of coins in the piggy bank. For (0, 54), this indicates the quantity of quarters when dimes are absent, while (0, 135) displays the number of dimes when there are no quarters.
<span>Real numbers can be either rational or irrational. sqrt(13) ≈ 3.60555 sqrt(14) ≈ 3.74166 A simple nearby rational approximation is 3.7 = 37/10. An example of an irrational number between them is sqrt(27/2).</span>
