The solution to a system of linear equations is the point at which the lines representing the linear equations intersect, let's graph to determine the solution:

As we can see on the graph, the lines intersect on (5, 2). Now, let's check substituing into the equations:

\begin{gathered} \text{Subtituing y=2, into the first equation:} \\ 2=x-3 \\ x=2+3 \\ x=5 \end{gathered}

So, the solution is correct.

<h3>How do we measure and calculate the distance in Geometry?</h3>

The distance between two points in geometry can be calculated by using the Pythagoras theorem.

Mathematically, the Pythagoras theorem can be expressed as:

\mathbf{d = \sqrt{x^2 +y^2}}

where;

  • x and y are opposite and adjacent sides respectively.

\mathbf{d = \sqrt{(9)^2 +(12)^2}}

\mathbf{d = \sqrt{81+144}}

\mathbf{d = \sqrt{225}}

d = 15 miles  

Therefore, we can conclude that they will be 15 miles apart after one hour if they left the same point at the same time.

Answer:

option 4 = 25

Step-by-step explanation:

given= chord js and hL intersects at poimt p

to find = value of x

solution:according to the therom;

if the line extensions of the chordJS and HL INTERSECTS at point K then their lenghts satisfy

JK×KS=HK×KL

10×30=X×12

300=12x

300/12=x

25= x
