Step-by-step explanation:

Graph D represents the inequality of the given Equation.

An inequality shows whether one value is less than, greater than, or simply not equal to another value by comparing them.

When two quantities are equal, we use the symbol "=," and when they are not equal, we use the symbol "≠". The first value can either be greater than (>) or less than (<).

Given equation 1/3(9x+27) > x+33

simplify the Equation

multiply both sides by 3 we get,

[1/3(9x+27)] 3 > (x+33)3

9x + 27 > 3x + 99

9x > 3x + 99 -27

9x - 3x > 72

6x > 72

x > 12

the Equation of inequality is x > 12

the line will be more than 12 and in which 12 is not included,

option D follows the required conditions, the empty circle in 12 shows 12 is not included and the line moves towards the positive side.

Hence option D is the correct representation of the given inequality.

Answer:

1/2

Step-by-step explanation:

Not sure but

I am assuming we have 8 integers :

All or (A) = {7,8,9,10,11,12,13,14} = n(A) = 8

Hence, the probability of any one outcome is 1/8.

Therefore, as you can detect, there are 4 numbers that are even numbers which means :

Even or (E) = {8, 10, 12, 14} = n(E) = 4

So, let E imply this occurrence

E x A

= 4 x 1/8

= 4/8

= 1/2

Probability of getting an even number from7 to 14 is equals to ( 1/ 2).

" Probability is defined as the mathematical calculation to represents the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

[tex]Probability = \frac{Number of favourable outcome }{Total number of outcomes}[/tex]

According to the question,

Given,

  Total number from 7 to 14 = { 7, 8, 9, 10, 11, 12, 13, 14}

⇒Total number of outcomes = 8

Possible outcomes of even number ={ 8, 10, 12, 14}

⇒ Number of favourable outcomes = 4

Substitute the value in the formula we get,

Probability = ( 4 / 8)

                  = ( 1 / 2) ( fraction in simplest form)

Hence, probability of getting an even number from7 to 14 is equals to ( 1/ 2).

Answer:

12-x=x+3

12-3=x+x

9=2x

9/2=x

4.5=x

Answer:

x = 3

Step-by-step explanation:

The segment parallel to the third side and intersecting 2 sides divides those sides proportionally, that is

[tex]\frac{12-x}{x+3}[/tex] = [tex]\frac{6}{4}[/tex] ( cross- multiply )

6(x + 3) = 4(12 - x) ← distribute parenthesis on both sides

6x + 18 = 48 - 4x ( add 4x to both sides )

10x + 18 = 48 ( subtract 18 from both sides )

10x = 30 ( divide both sides by 10 )

x = 3

Answer: 31, hope this helps❤

Step-by-step explanation:

If f(4) = 22, then the value of f(1) is 31.

A sequence in mathematics is a ordered set of objects or numbers which are related with something.

For example, 1, 3, 5, ..... is a sequence of odd numbers.

Given a sequence defined as,

f(n + 1) = f(n) - 3

Given,

f(4) = 22

We know from definition,

f(4) = f(3) - 3

So, f(3) = 22 + 3 = 25

Similarly,

f(2) = 25 + 3 = 28

f(1) = 28 + 3 = 31

Hence the correct option is 31.

Answer:

The length needed to cut off is 12.55 cm

Step-by-step explanation:

The corrected question is:

you need a piece of paper to measure 64.25 cm. If you tape two together that each measure 38.4 cm, how much do you need to cut off?

Solution:

measurement/length of each paper piece = 38.4 cm

measurement/ length required = 64.25 cm

If length of one paper piece is 38.4 cm then if we tape 2 pieces together then the measurement or length is calculated as:

38.4 + 38.4 = 76.8 cm

So to calculate how much we need to cut off:

length required to cutoff = total length of two pieces - length  required

                                         = 76.8 - 64.25

                                         = 12.55 cm

So the length required to cut off is 12.55 cm

Answer:

PT= 130

Step-by-step explanation:

Since T is the midpoint of segment PQ,

PT = TQ

7x - 24 = 6x-2

Subtract 6x both sides and add 24 both sides

7x -6x - 24 = 6x -6x -2

x - 24 + 24 = -2 + 24

x= 22

Substitue x into PT

7(22) - 24

154 - 24

PT= 130
