Answer:
( 5 , 10 )
Step-by-step explanation:
Solution:-
- There are two ships, A and B, currently located by their respective coordinates in the cartesian coordinate system:
<u>Position of ship A: ( - 1 , -2 )</u>
<u>Position of ship B: ( -4 , 1 )</u>
- Both ships try to locate a lifeboat. The spotlights used by each ship are modelled as straight line functions of cartesian coordinate originating from their respective ships.
- Spot lights for each ship were able to locate the same lifeboat. The respective spotlights are modelled by the following functions:
<u>Spotlight Ship A: y = 2x</u>
<u>Spotlight Ship B: y = x + 5 </u>
- To locate the position of the lifeboat with respect to the origin ( 0 , 0 ) we will use the spotlight model functions and equate them. This is because the spotlights must converge or meet at the position of lifeboat provided the lifeboat is found by both ships.
- Therefore,
Spotlight A = Spotlight B
y = 2x = x + 5
2x = x + 5
x = 5 , y = 10
<u>Answer:</u> <em>The two spotlight meet at the coordinates ( 5 , 10 ). This is also the position of the lifeboat located by both the ships</em><em>. </em>
Answer:
Step-by-step explanation:
First you need to get like items on the same side(put the variables on one side and the non-variables on the other). Remember anything you do on one side of the equal, you have to do on the other side, too.
5X+3=7X-1 I'm going to move the -1 first, but you don't have to as long as you keep the equation equal.
5X+3+1=7X-1+1 We know that +1-1 is zero and so is -1+1. So
5X+3+1=7X We don't need to keep that zero.
5X+4=7X Now, we want to move the 5X over.
5X-5X+4=7X-5X Simplify and get rid of the zero.
4=2X Last, we have to divide to get the 2 away from the X.
4/2=2X/2 Not everyone know that slash mean divide, :-).
2=X
