x=4

Step-by-step explanation:

Answer:

x = 27/16

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define equation

x + 5/9x = 2(3 - x)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 21/8 does indeed equal 21/8.

∴ x = 27/16 is a solution to the equation.

The length and width of another rectangular lot that has the same perimeter but a smaller area will be 140 and 65m

It should be noted that perimeter is calculated as:

Perimeter = 2(Length + Width)

Perimeter = 2(120 + 85)

Perimeter = 410m

Therefore, the length and width of another rectangular lot that has the same perimeter but a smaller area will be 140 and 65.

The area will be:

= 140m × 65m

= 9100m²

This is smaller than (120 × 85) = 10200m².

Parabola

Step-by-step explanation:

A parabola will be formed when a plane intersects the central axis at 50°

It is defined as the graph of a quadratic function that has something bowl-shaped.

The angle between the generator and the central axis of a double-napped cone is 50° and a plane intersects the central axis at 50°

Ф = ∅

Where Ф is the angle between the vertical axis and plane and

∅ is the angle between the generator and central axis.

When both angles are the same the parabola is formed by the intersection of the plane.

Thus, a parabola will be formed when a plane intersects the central axis at 50°

The valid values of x is x = 36

The equation is given as

16 - √x = 10

Subtract 16 from both sides of the equation

So, we have

√x = -6

Take the square of both sides of the equation

So, we have

x = 36

Hence, the valid values of x is x = 36

Answer:

77 degrees c:

Step-by-step explanation:

Answer:

z=118 y=21

Step-by-step explanation:

for z

since 2 sides of a line should equal 180 degrees, subtract 62 from 180

180-62=118 since z and the side opposite of 62 are congruent so

z=118

for y

62 and [tex]5y-43[/tex] are congruent so set them equal to each other and solve:
[tex]5y-43=62\\5y=105\\\\y=21[/tex]

Answer:

(x, y ) → (x - 2, y - 5 )

Step-by-step explanation:

A shift of 2 units left is equivalent to subtracting 2 from the x- coordinate.

A shift of 5 units down is equivalent to subtracting 5 from the y- coordinate.

Thus transformation rule is

(x, y ) → (x - 2, y - 5 )

Answer:

0.06

Step-by-step explanation:

let 0.09 be a1

and 0.15 be a2

and 0.21 be a3

common difference = a2-a1 or a3-a2

a2-a1= 0.15-0.09 = 0.06

a3-a2= 0.06

hence the common difference in the ap in 0.06

Step-by-step explanation:

This doesn't make sense.

The range of the function represented by the graph is 1 < y < 8

The domain of the function is the set of input values of the graph

The range of a function is the set of output values of the graph.

The graph represents the given parameters

On the graph, we have the following endpoints

Closed circle at (-13, 4)

Open circle at (11, 1)

Maximum = (4, 8)

The definition of the range implies that the range of a function is the set of y values of the graph.

Recall that

Closed circle at (-13, 4)

Open circle at (11, 1)

Maximum = (4, 8)

Remove the larger y value of the endpoints

Open circle at (11, 1)

Maximum = (4, 8)

Remove the x coordinates

So, we have

Open circle at (1)

Maximum = (8)

Combine the y values

1 < y < 8

Hence, the range of the function is 1 < y < 8

Answer:

x = 1/6

Step-by-step explanation:

Subtract 4 from both sides of the equation.

3x + 4 - 4 = 9x + 3 - 4

Simplify, subtract the numbers.

3x = 9x - 1

Subtract 9x from both sides of the equation.

3x - 9x = 9x - 1 - 9x

Simplify, combine like terms.

-6x = -1

Divide both sides of the equation by the same term.

-6x/-6 = -1/-6

Simplify, cancel terms that are in both the numerator and denominator, and divide the numbers.

x = 1/6

The solution to the given equation 3x + 4 = 9x + 3 is x = 1/6.

The equation is given as follows:

3x + 4 = 9x + 3

To solve the equation 3x + 4 = 9x + 3 for x, we need to isolate the variable x on one side of the equation.

Start by subtracting 3x from both sides of the equation to move all the terms involving x to one side:

3x - 3x + 4 = 9x - 3x + 3

4 = 6x + 3

Next, subtract 3 from both sides to isolate the term with 6x on the right side:

4 - 3 = 6x + 3 - 3

1 = 6x

Divide both sides of the equation by 6 to solve for x:

(1)/6 = (6x)/6

1/6 = x

Thus, the solution to the equation is x = 1/6.
