Solve this system of equations using the substitution method.

miskamm [114]

Answer:

(5,14)

Step-by-step explanation:

4x-6=2x+4 because I chose any of the y values

change of subjects ⬇️

4x-2x =4+6

2x=10

2x÷2 and 10÷2

⬆️ making x stand alone

x= 5

put x into any of the equation

y=2(5)+4

y= 10+4

y=14

Find the perimeter of the polygon. Round your answer to the nearest tenth.

dimulka [17.4K]

The perimeter of the polygon is 26.1 units.

To find the perimeter of the polygon.

<h3>What is polygon?</h3>

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

Given that:

Distance between points $(x_{1} ,y_{1} )$ , $(x_{2} ,y_{2} )$ is given by

$\sqrt{(x_{2} -x_{1} )^{2}+(y_{2} -y_{1} )^{2} }$

As per the graph,

point Q is (2,0)

point R is (4,5)

point S is (8,7)

point T is (6,4)

point U is (10,3)

QR= $\sqrt{(4 -2 )^{2}+(5 -0 )^{2} }=\sqrt{4+25} =\sqrt{29}$ $=5.38 units$

RS= $\sqrt{(8 -4 )^{2}+(7 -5 )^{2} }=\sqrt{16+4} =\sqrt{20}$ $=4.47 units$

ST= $\sqrt{(6 -8 )^{2}+(4 -7)^{2} }=\sqrt{4+9} =\sqrt{13}$ $=3.60 units$

TU= $\sqrt{(10 -6 )^{2}+(3 -4 )^{2} }=\sqrt{16+1} =\sqrt{17}$ $=4.12 units$

QU= $\sqrt{(10 -2 )^{2}+(3 -0 )^{2} }=\sqrt{64+9} =\sqrt{73}=8.54 units$

Perimeter refers to sum of lengths of all the sides.

Perimeter =5.38+4.47+3.60+4.12+8.54=26.1 units

So. the perimeter of the polygon is 26.1 units.
