After solving each system, 4y = 2x , 2x + y = (x/2) + 1 , the values of x and y are calculated to be 0.5 and 0.25 respectively.

The first equation, 4y = 2x is a linear equation whereas the second equation, 2x + y = (x/2) + 1 is considered a rational equation as it contains a fraction.

By rearranging the linear equation, the value of x can be found to be,

4y = 2x

x = 4y ÷ 2

x = 2y

Putting the calculated value of x in the rational equation,

2x + y = (x/2) + 1

2(2y) + y = (2y/2) + 1

4y + y = y + 1

Rearranging,

4y + y - y = 1

4y = 1

y = 1/4 = 0.25

To solve for x, put y = 0.25 in the linear equation as follows,

4y = 2x

4(0.25) = 2x

1 = 2x

x = 1/2 = 0.5

Thus the value of x and y in these systems are calculated to be 0.5 and 0.25 respectively.

After calculating the value of x in the all angle sum equation of ΔRST, we have come to find that m∠S = 38°.

An angle is a figure generated by two rays or lines that have a common terminal in Plane Geometry. The term "angle" is derived from the Latin word "angulus," which meaning "corner." The two rays are known as the sides of an angle, while the common terminus is known as the vertex.

The plane angle does not have to be in Euclidean space. Dihedral angles are created by the intersection of two planes in Euclidean or other space. An angle is identified by the symbol "∠". The angle measurement between the two beams can be represented by the Greek letter θ,α, β etc.

We have given that

m∠R = (x+17)°

m∠S = (2x−2)°

m∠T = (5x+5)°

We know all the angles of a triangle add upto 180°

m∠R + m∠S + m∠T = 180°

(x+17)° + (2x−2)° + (5x+5)° =180°

8x + 20 = 180°

8x = 160°

x = 160°/8

x = 20°

And therefore, m∠S = (2(20)−2)°

                                  = (40 - 2)°

Smallest odd number = 2x + 1   The one guarantees that the number is odd. The 2 in front of the x makes sure it is even to start with.

The larger odd number is 2x + 3.

Equation

2x + 1 + 3(2x + 3) = 330                    Remove the Brackets

2x + 1 + 6x + 9 = 330                       Combine

8x + 10 = 330                                  Subtract 10 from both sides.

8x +10-10 = 330 - 10                        Combine

8x= 320                                           Divide both sides by 8

x = 40

Answer

2x + 1 = 2*40 + 1 = 81

Answer:

x= 8, z= 118

Step-by-step explanation:

To find x, solve the equation with the one unknown x given by supplementary angles definition.

Supplementary angles sum up to 180° there for

8x +54 + 7x +6 = 180, group like terms

8x + 7x = 180 -54-6, combine like terms

15x = 120, divide both sides by 15

x = 8

To find z, solve for z the equation given by vertical angles definition.

Vertical angles are congruent there for

8x +54 = z, substitute x for 8

8·8 +54 = z, multiply then add

z = 118

Based on the definition of supplementary angles, x = 8; z = 118

Based on the definition of supplementary angles we have:

7x + 6 + 8x + 54 = 180

Solve for x

15x + 60 = 180

15x = 180 - 60

15x = 120

x = 120/15

x = 8

z = 8x + 54 (vertical angles)

Plug in the value of x

z = 8(8) + 54

z = 118

The equation in slope-intercept form for the line that passes through (-0,7), parallel to y = 4x-19 is y = 4x + 7.

The slope intercept form of a line is:-

y = mx + b

Where:-

m represents the slope of a line

b represents the y-intercept of a line

x and y represent the ordered pairs (x,y) throughout a line

We are given the line y = 4x-19 is parallel to the line whose equation we have to find.

Hence,

slope of the line = 4 = slope of the given line

Also, (0,7) passes through the line,

Hence,

The triangle having vertices X(1,2), Y(4,6), Z(6,6) is obtuse.

According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:

XY = [tex]\sqrt{(4-1)^{2} + (6 - 2)^{2} }[/tex]

∴ XY = 5

YZ = [tex]\sqrt{(6 - 4)^{2} + (6 - 6)^{2} }[/tex]

∴YZ = 2

ZX = [tex]\sqrt{(6 - 1)^{2} + (6 - 2)^{2} }[/tex]

∴ ZX = 6.4

∴The longest side is ZX = 6.4

Hence, a = XY, b = YZ and c = ZX;

Consider          [tex]a^{2} + b^{2}[/tex]:

= [tex]XY^{2}[/tex] + [tex]YZ^{2}[/tex]

A translation maps one triangle onto the other. Each pair of corresponding sides has the same measure, so they are congruent. △MNO ≅ △QRS by SSS.

What exactly do you mean by congruent?

Use the Distance Formula to find the lengths of.

MN , NO , OM

MN has end points M(4 , 7)  And N( 5, 4 )

MN = [tex]\sqrt{ (x_{2} - x_{1}^{2}+ ( y_{2} - y_{1} )^{2}[/tex]

      = [tex]= \sqrt{(1)^{2} + ( -3)^{2} }[/tex]

       [tex]= \sqrt{ 1 + 9 }[/tex]

         [tex]= \sqrt{10}[/tex]

NO has end points N(5, 4) and O(2, 3).

NO = √( 2 - 5 )² + ( 3- 4 )²

      = √( - 3)²  + ( -1)²

      = √ 9 + 1 = √10

OM has end points O(2, 3) and M(4,7)

OM = √( 4 - 2 )² + ( 7 - 3 )²

      = √ (2)²  + ( 4 )²

       = √20

Similarly, find the lengths of QR, RS , SQ

QR has end points Q(2, 5) and R(3, 2).

QR = √( 3 - 2)² + ( 2 - 5 )²

     = √(1)² + ( -3)²

     = √ 1 + 9

      = √10

RS has end points R(3, 2) and S(0, 1).

RS = √( 0- 3)² + ( 1 - 2 )²

     = √( -3)² + (-1)²

      = √9 + 1 = √10

SQ has end points S(0, 1) and Q(2, 5).

SQ = √ ( 2 - 0 )² + ( 5 - 1 )²

      = √ 4 + 16  = √20

So, MN ≅ QR , NO ≅ RS and OM ≅ SQ
