Answer:

Length of JK is 68.27 units.

Step-by-step explanation:

By applying geometric mean theorem (leg theorem) in the triangle attached,

[tex]\frac{KL}{KM}= \frac{JK}{KL}[/tex]

(KL)² = (KM)(JK)

(32)² = (15)(x)

x = [tex]\frac{1024}{15}[/tex]

x = 68.2666

x ≈ 68.27

Therefore, length of JK is 68.27 units.

Answer:

s=6

Step-by-step explanation:

Hope this helps :)

The value of s for the given expression 3(s + 4 = 30 will be 6.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

3(s + 4) = 30

Divide both sides by 3

s + 4 = 10

Subtract both sides by 4

s + 4 - 4 = 10 - 4

s = 6

Hence "The value of s for the given expression 3(s + 4 = 30 will be 6".

Step-by-step explanation:

The Tommy's class collect the amount of 14 dollar.

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.

We need to find the solutions of the equation 2(x + $3.00)= $34.00 ;

Now solving for x;

2(x + $3.00)= $34.00

Open the bracket;

2x + 6 = 34

Combine the like terms;

2x = 34 - 6

2x = 28

x = 14

Therefore, the equation 2(x + $3.00)= $34.00 has only one solution which is 14.

F(x) = 43/16 (43 over 16)

Given:

The figure of a polygon.

To find:

The area of the polygon.

Solution:

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]

Area of trapezoid is

[tex]Area=\dfrac{1}{2}(a+b)h[/tex]

Where, a, b are bases and h is the height.

The area of the triangle with base 6 cm and height 8 cm is

[tex]A_1=\dfrac{1}{2}\times 6\times 8[/tex]

[tex]A_1=24[/tex]

Height of the trapezoid is [tex]13-8=5\ \text{cm}[/tex] and the bases are 6 cm, 12 cm. So, the area of the trapezoid is

[tex]A_2=\dfrac{1}{2}(6+12)(5)[/tex]

[tex]A_2=\dfrac{1}{2}(18)(5)[/tex]

[tex]A_2=(9)(5)[/tex]

[tex]A_2=45[/tex]

Now, the total area of the polygon is

[tex]A=A_1+A_2[/tex]

[tex]A=24+45[/tex]

[tex]A=69[/tex]

Therefore, the area of the polygon is 69 sq. cm.

Answer:

  a)  x = ±5

  b)  x = ±√11 ≈ ±3.317

Step-by-step explanation:

Since we want x for some function value, it is convenient to determine the inverse function.

  x = g(y)

  x = y^2 -5

  x +5 = y^2

  y = ±√(x +5)

__

a) x = ±√(20 +5) = ±5

b) x = ±√(6 +5) = ±√11 ≈ ±3.317

Given:

A figure in which a transversal line intersect two parallel lines.

[tex]m\angle 2=4x+7, m\angle 7=5x-13, m\angle 5=68[/tex] and [tex]m\angle 3=3y-2[/tex].

To find:

The value of x and y.

Solution:

We know that, if a transversal line intersect two parallel lines, then

(1) Alternate exterior angles are equal.

(2) Same sided interior angles are supplementary. So their sum is 180 degrees.

In the given figure j and k are parallel lines and l is a transversal line.

From the given figure, it is clear that,

[tex]m\angle 2=m\angle 7[/tex]                (Alternate exterior angles are equal)    

[tex]4x+7=5x-13[/tex]

[tex]7+13=5x-4x[/tex]

[tex]20=x[/tex]

Therefore, the value of x is 20.

Now,

[tex]\angle 3+\angle 5=180[/tex]     (Same sided interior angles are supplementary)

[tex]3y-2+68=180[/tex]

[tex]3y+66=180[/tex]

[tex]3y=180-66[/tex]

[tex]y=\dfrac{180-66}{3}[/tex]

[tex]y=\dfrac{114}{3}[/tex]

[tex]y=38[/tex]

Therefore, the value of y is 38.

Answer:

Options (C), (D) and (E)

Step-by-step explanation:

Slope of the given line = [tex]\frac{1}{3}[/tex]

Any line having same slope will be parallel to the given line otherwise the lines will intersect.

Therefore, we will find the slope of the lines passing through two points given in the options.

Option A

Slope of the line passing through (12, -13) and (15, -12)

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{-13+12}{12-15}[/tex]

   = [tex]\frac{1}{3}[/tex]

Therefore, both the lines are parallel having no point of intersection.

Option B

Slope = [tex]\frac{-9+7}{18-24}[/tex]

          = [tex]\frac{1}{3}[/tex]

Both the lines are parallel having no point of intersection.

Option C

Slope = [tex]\frac{-20+21}{15-18}[/tex]

          = [tex]-\frac{1}{3}[/tex]

Therefore, both the lines will intersect.

Option D

Slope = [tex]\frac{-15+14}{30-36}[/tex]

          = [tex]\frac{1}{6}[/tex]

Both the lines will intersect each other.

Option E

Slope = [tex]\frac{-11+10}{24-30}[/tex]

          = [tex]\frac{1}{6}[/tex]

Both the lines will intersect each other at a point.

Options (C), (D) and (E) are the correct options.

Answer:

The solutions are x = -7 and x = -9

Step-by-step explanation:

All absolute values are non-negative numbers, so x + 8 will always be greater than 0. This means that |x + 8| = 1 can be represented as x + 8 = 1 AND x + 8 = -1.

x + 8 = 1 ⇒ x = -7

x + 8 = -1 ⇒ x = -9

So the solutions are x equals -7 or -9.

Answer:

x = 4

Step-by-step explanation:

We have the algebraic expression 3x + 16 = 7x and are asked to solve.

When we need to solve for x, we need to get x alone always.

So 3x + 16 = 7x.

Subtract 3x from both sides :

16 = 4x

Divide 4 from both sides :

x = 4

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Given

[tex]3x + 16 = 7x[/tex]

Step 1

[tex]16 = 7x - 3x \\ 16 = 4x[/tex]

Step 2

[tex] \frac{16}{4} = x \\ 4 = x[/tex]

Step 3

[tex]3x + 16 = 7x \longrightarrow 3(4) + 16 = 7(4) \\ 12 + 16 = 28 \\ 28 = 28[/tex]

The equation is true for x = 4. Hence, the solution is x = 4
