The area of the polygon with the given vertices is of 7.5 square units.

<h3>What is the area of a right triangle?</h3>

The area of a right triangle is given by half the multiplication of the lengths of it's sides.

The polygon in this problem is a right triangle with sides 3 and 5, hence the area is given by:

A = 0.5 x 3 x 5 = 7.5 square units.

Solve for x and explain the steps: 3x-6=4(2-3x)-8x

mote1985 [20]

Answer: x = 14/23

Step-by-step explanation:

3x-6=4(2-3x)-8x

3x-6=8-12x-8x --> Expand 4(2-3x)

3x-6=8-20x --> Collect like terms

3x-6+6=8-20x+6 --> Add 6 to both sides, to remove it from the right side

3x=-20x+14

3x+20x=-20x+14+20x --> Add 20x to both sides, to remove it from the left side

23x=14

$\frac{23x}{23}=\frac{14}{23}$ --> Divide both sides by 23

x = 14/23

Please help ;-; Solve for the simultaneous equation…. 5x+y=17 X+y=3

Svetach [21]

Given Equation:-

5x+y=17 . . . . . . . . 1
x+y=3 . . . . . . . . . . 2

To find :

value of x
value of y

Solution :

Let's start with equation 2:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

5x+y=17
5x + (3 - x) = 17
5x - x + 3 = 17
4x + 3 = 17
4x = 17 - 3
4x = 14
x = 14/4
x = 7/2
x = 3.5

Now Let's find value of y:

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = 0.5

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -x + 1

2x + 3y = 6

Step 2: Solve for x

Substitution

Substitute in y: 2x + 3(-x + 1) = 6
Distribute 3: 2x - 3x + 3 = 6
Combine like terms: -x + 3 = 6
Isolate x terms: -x = 3
Isolate x: x = -3

Step 3: Solve for y

Define equation: y = -x + 1
Substitute in x: y = -(-3) + 1
Simplify: y = 3 + 1
Add: y = 4
