[tex]\sqrt[3]{4x-4}=6[/tex]

Begin by cubing each side of the equation to get rid of the cubic root.

[tex](\sqrt[3]{4x-4})^3=(6)^3\\ 4x-4=216[/tex]

add 4

[tex]4x-4+4=216+4\\4x=220[/tex]

Divide by 4

[tex]\frac{4x}{4}=\frac{220}{4}[/tex]

Answer:

480

Step-by-step explanation:

First add the numbers in the table together and put the total as a denominator in a fraction then the amount of times 2 odd numbers appeared as the numerator then put another fraction with 2,000 as the denominator and divide 2,000 by the total then multiply the numerator by that answer to get the correct answer.

Hope this helped!

Using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

A fraction is " a number is expressed as a quotient  in which numerator is divided by denominator".

According to the question,

Kelly rolls two number cubes 50 times, each cube is even (E) or odd (O).

The graph shows frequency of two numbered cube roll. The frequency of getting EO is 14, frequency of getting OE is 8, frequency of getting EE is 16 , frequency of getting OO is 12.

Total number of frequency = 14 + 8 + 16 + 12

= 50

The fraction of getting two odd numbers when cube is rolled 50 times

= [tex]\frac{12}{50}[/tex].               →(1)

In order to find, when two number cubes are rolled 2,000 times the number of times two odd numbers will occur.

= [tex]\frac{x}{2000}[/tex].            →(2)

Equating two fraction, to get value of 'x'.

[tex]\frac{12}{50} = \frac{x}{2000}[/tex]

[tex]\frac{12*2000}{50}[/tex]  = x

x = 12 × 40

x = 480.

Hence, using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

Answer:

The answer is D

Step-by-step explanation:

I subtracted 10 from 75 and got 65 then divided 65 by 3 and got 21

The answer is c.

An inequality solution is any value of the variable that makes the inequality true. Solving linear inequalities is almost exactly like solving linear equations.

How to find which value for x will make 3x + 10 > 75 correct?

Subtract 10 from both sides we get , 3x+ 10 - 10 = 75 - 10

3x + 0 > 65

divide both sides by 3 implies

3x / 3 = 65 /3

=> x > 15.

Thus Option c is correct.

Answer:

V =221.4 m^3

Step-by-step explanation:

The volume is given by

V = Bh

Where B is the area of the base

The base is the triangle

B = 1/2 (12) * 4.1

B = 24.6

The height of the figure is 9

V = 24.6 *9

V =221.4 m^3

Answer:

221.4 m³

Step-by-step explanation:

Volume = base area × height

Base area: ½ × 4.1 × 12 = 24.6 m²

height: 9 m

Volume = 24.6 × 9 = 221.4 m³

Answer:

d. 2x^2-8x

Step-by-step explanation:

ure just doing distributive property.

The product of 2x(x-4) is 2x² - 8x

In a mathematics, algebraic expressions can be in bracket. This bracket means we multiply all the variables outside by those inside.

According to this question, we are given the following expression: 2x(x-4)

This means that 2x multiples x and -4 independently.

That is; 2x × x and 2x × -4

2x² - 8x

Therefore, the product of 2x(x-4) is 2x² - 8x.

Answer:

Step-by-step explanation:

It is given that y varies inversely with x.

[tex]y\propto \dfrac{1}{x}[/tex]

[tex]y=\dfrac{k}{x}[/tex]       ...(i)

where, k is constant of proportionality.

It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.

[tex]-105=\dfrac{k}{-3}[/tex]

[tex]-105\times (-3)=k[/tex]

[tex]315=k[/tex]

Now,

[tex]y=\dfrac{315}{x}[/tex]

Substitute x=15 in the above equation.

[tex]y=\dfrac{315}{15}[/tex]

[tex]y=21[/tex]

Therefore, the value of y is 21 when x=15.

Step-by-step explanation:

-5+6=1

-9-23=-32

1+-32=-31

Answer:

The answer is -31

Step-by-step explanation:

First, you would add everything in the parenthesis. Negative 5 added to 6 gives you a sum of 1, while negative 9 subtracted from 23 would give you negative 32. Once you have these two values, simply combine the totals to get negative 31

(1) + (-32) = -31   :)

Answer:

                                = 0 + (-10)

                                = (-10)

(-4) + 4 = 0

-20 + 10 = -10. When two numbers have different  sign, subtract and the result will have the sign of the bigger number. Here bigger number is 20 and So the result has a negative sign

Answer:

The answer is -10.

Step-by-step explanation:

-4 + 4 = 0

-20 - - 10 = -10

−30=5(x+1)

Step 1: Simplify both sides of the equation.

−30=5(x+1)

−30=(5)(x)+(5)(1)(Distribute)

−30=5x+5

Step 2: Flip the equation.

5x+5=−30

Step 3: Subtract 5 from both sides.

5x+5−5=−30−5

5x=−35

Step 4: Divide both sides by 5.

5x5=−355

x=−7

Answer:

x=−7

Answer:

x = -7

Step-by-step explanation:

Since this problem has the distributive property, we can simplify the problem.

-30 = 5x + 5

Now we have to subtract 5 from both sides because of the +5.

-35 = 5x

To find the answer, we have to move all the real numbers to one side, the variable on the other. To do this, we can simply divide both sides by 5.

Step-by-step explanation:

A rotation of 90° about the origin includes the interchange of the position of  x, and y in the ordered pair and a change of one of the signs of the pair.

The option that shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin is the option;

Reasons:

The given transformation the gives the X'Y'Z' = 90° rotation about the origin

The given coordinates of X'Y'Z' are;

X'(-2, 2), Y'(0, 6), and Z'(1, 1)

Required:

The figure that shows the preimage of X'Y'Z'

Solution:

Given that X'Y'Z' is obtained by the rotation of XYZ 90°, therefore, the

coordinates of XYZ are given by the rotation of X'Y'Z' in the reverse

direction either counterclockwise and clockwise.

(x, y) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] (-y, x)

(x, y) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex] (y, -x)

Therefore, we have;

X'(-2, 2) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] X(-2, -2)

Y'(0, 6) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] Y(-6, 0)

Z'(1, 1) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] Z(-1, 1)

Similarly, we get;

X'(-2, 2) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex]  X(2, 2)

Y'(0, 6) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex]  Y(6, 0)

Z'(1, 1) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex] Z(1, -1)

The above coordinates of XYZ; X(2, 2), Y(6, 0), and Z(1, -1), corresponds to

the option;

On a coordinate plane, a triangle has points X(2, 2), Y(6, 0), and Z(1, -1).

Therefore, XYZ was rotated 90° clockwise to form X'Y'Z'
