Answer:

x = 5

Step-by-step explanation:

Let

x = the unknown variable

The difference of 11 and 2 times a number "x" is 1

11 - 2x = 1

Find x

11 - 2x = 1

Add 2x to both sides

11 - 2x + 2x = 1 + 2x

11 = 1 + 2x

Subtract 1 from both sides

11 - 1 = 1 + 2x - 1

10 = 2x

Divide both sides by 2

10 / 2 = 2x / 2

5 = x

x = 5

Answer:

y = -3x + 18

Step-by-step explanation:

The slope intercept form of a line is expressed as y = mx+c

m is the slope

b is the intercept

Get the slope

Given the equation of a line 9x + 3y = 6

Rewrite

3y = -9x + 6

y = -9x/3 + 6/3

y = -3x + 2

Hence the slope of the line is -3

Get the y-intercept

Substitute m = -3 and (5,3) into y  = mx+b

3 = -3(5) + b

3 = -15 + b

3 + 15 = b

18 = b

b = 18

Get the required equation

y = mx+b

y = -3x + 18

This gives the required equation

Answer:

{-3, 3}

Step-by-step explanation:

x^2 - 9 = 0 can be written in factored form as (x -3)(x + 3) = 0.  Letting each factor equal zero separately and solving for x, we get x:  {-3, 3}

The height of the house is √175 feet if the piece of wire 16 feet long is strung from the top of the side of a house to the ground. option (C) is correct.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

As we can see the wire, wall and base making a right angle triangle;

So applying the Pythagoras theorem:

Supposing the length of the wall is x feet

16² = 9² + x²

x²= 175

x = √175 feet

Thus, the height of the house is √175 feet if the piece of wire 16 feet long is strung from the top of the side of a house to the ground. option (C) is correct.

Answer:

3619.6cm^3

Step-by-step explanation:

Given data

Daimeter= 24cm

Radius= 12cm

The formula for finding the volume of the hemisphere is given below

V = 2/3*π*r³

Substitute

V= 2/3*3.142*12^3

V=  2/3*3.142*1728

V= 10858.752/3

V=3619.6cm^3

Hence the volume is 3619.6cm^3

Answer:

G = (y-x)/2

Step-by-step explanation:

Here, we want to find the value of the angle marked G

To do this, we are going to use one of the important circle angle-arc relationships

Thus, we have it that;

G = 1/2 (mFE - mJH)

G = 1/2 (y-x)

Which is simply

G = (y-x)/2

Answer:

9

Step-by-step explanation:

We can see that 6 is 2 more than 3, and so the difference is -3^2, 9.

We can check this by seeing that -3^6 is -729 and -3^4 is -81.

We have

                        -729 / -81 = 9.

Answer: 9

Step-by-step explanation:

The equation for the graph is y = sin[(1/2)x] after applying the transformation x → (1/2)x option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

A graph of a trigonometric function is shown in the graph:

From the graph of a function, we can see the sin function represented by the graph.

y = sin(x)

To find the equation for the graph we can apply the transformation to the above equation.

From the graph

x =2π

y = 0

x → (1/2)x

y = sin[(1/2)x]

Thus, the equation for the graph is y = sin[(1/2)x] after applying the transformation x → (1/2)x option (C) is correct.

Answer: 523.1 mm^2

You first want to find the radius for the volume of cylinder formula. You first do 14 divided by 2 to get the radius. You should get 7. Then after you find the radius you then put it into the formula which is v=3.14 x radius^2 x height. The equation with all the numbers from the problem is 3.14 x 7^2 x 3.4. After you put the equation into your calculator you should get 523.1 mm^2.

Answer:

x = 3 units

SV = 2 units

Step-by-step explanation:

In[tex] \odot Z[/tex] QR and ST are chords such that:

QR = ST = 4

That is both the chords are equal in measure.

Equal chords are at equal distance from the center of the circle. Therefore,

VZ = UZ

4x - 6 = 6

4x = 6 + 6

4x = 12

x = 12/4

x = 3 units

Since, perpendicular dropped from the center of the circle bisects the chord.

[tex] \therefore SV = \frac{1}{2} ST[/tex]

[tex] \therefore SV = \frac{1}{2} \times 4[/tex]
