Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
0.5t = 0.2 + 0.4t
<u>Step 2: Solve for </u><em><u>t</u></em>
- [Subtraction Property of Equality] Subtract 0.4t on both sides: 0.1t = 0.2
- [Division Property of Equality] Divide 0.1 on both sides: t = 2
To find an inverse matrix you first have to find the determinant and then put the absolute value of it under a 1. That's what is sitting outside in front of all those matrices. What you have to do now is multiply that determinant by what I teach to my students as the "mixed up matrix". They always remember from that. Change the position of the terms on the major axis (here they are a and d), and then switch the signs on the other 2 terms. Our inverse matrix then is
Answer:
About 2:18
- The minute hand points toward the marker, meaning that is 15 minutes.
- Count the other ticks, and that's 18.
- Since the hand is not exactly on the 3, that means it is 2:00
With this information, we can make a hypothesis or come to a conclusion that the clock says 2:18
