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]

Which of the following is equivalent to 7(a + 4) + 15?

7a + 43
7a + 19
7a + 60
28a + 15

Answers

Answer:

7a + 43

Step-by-step explanation:

Let's simplify step-by-step.

7(a+4)+15

Distribute:

=(7)(a)+(7)(4)+15

=7a+28+15

Combine Like Terms:

=7a+28+15

=(7a)+(28+15)

=7a+43

Answer:

7a + 43

Step-by-step explanation:

Given:

7(a + 4) + 15

Solve:

Distribute:

7(a + 4) + 15

7 × a = 7a7 × 4 = 28

Now we have:

7a + 28 + 15

Add the numbers:

28 + 15 = 43

7a + 43

Therefore, 7a + 43 is equivalent to 7(a + 4) + 15.

x +5/9x=2{3-x}
How do i solve it

Answers

Answer:

x = 27/16

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define equation

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

Step 2: Solve for x

Distribute 2: x + 5/9x = 6 - 2xCombine like terms: 14/9x = 6 - 2xAdd 2x on both sides: 32/9x = 6Divide 32/9 on both sides: x = 27/16

Step 3: Check

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

Substitute in x: 27/16 + 5/9(27/16) = 2(3 - 27/16)Multiply: 27/16 + 15/16 = 2(3 - 27/16)Subtract: 27/16 + 15/16 = 2(21/16)Multiply: 27/16 + 15/16 = 21/8Add: 21/8 = 21/8

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

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

What are the valid values of x in:
16−−√+x=10

Answers

The valid values of x is x = 36

How to determine the valid values of x?

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

Solve for x: 3x + 4 = 9x + 3

Answers

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.

Answers

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 )

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

What is the domain of a function?

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

What is the range of a function?

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

How to determine the domain and the range?

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

HELP ME FIND X ASWELL PLEASE USING THE SAME KITE

Answers

All kites equal to 360 degrees X = 99 degrees and y= 54 degrees. Side A would be 153 degrees I believe

Answer:

a=18units

x=99°

y=108°

Step-by-step explanation:

Perimeter=sum of lengths around the kite.

Given that two sides each are congruent:

P=12+12+a+a

60=24+2a

60-24=2a

36=2a

a=36/2=18

x=99°

The angle between the generator and the central axis of a double-napped cone is 50°. Which conic section is formed when a plane intersects the central axis at 50°?

circle

parabola
hyperbola

Answers

Answer:

Parabola

Step-by-step explanation:

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

What is a parabola?

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°
