The system of equation which have no solution are A, B and D.

Slope defines rate of change or we can also say it is rise over run.

According to the given question we have to determine given system of equations which have no solution.

We know when two lines are parallel to each other they have no solution cause they have no common intersection points and we also know parallel lines have same slope with different y intercept.

Let us write all the system of equations in slope intercept form which is

y = mx + b.

A.

y = -3x + 5.

y = -3x + 4.

This system of equation has no solution cause have have same slope and different y intercept hence parallel to each other.

B.

y = 4x - 1.

4y = 16x - 1

y = 4x - 1/4.

Same slope different y intercept so no solution.

C.

-2y = -5x + 3.

y = (5/2)x - 3/2.

-4y = -10x + 6.

y = (5/2)x - 3/2.

Same slope same y intercept so they are on top of another so infinite no. of solutions.

D.

3x + 7y = 42

7y = - 3x + 42.

y = (-3/7)x + 6.

14y = -6x + 50.

y = (-3/7)x + 25/7.

Same slope different y intercept so they are parallel to each other.

E.

y =2x + 5.

y = 5x².

Different slope and y intercept so they are not parallel.

Answer: Option C.

Step-by-step explanation:

x = 10.8

A. = 4,320 ÷ x

= 4,320/10.8

= 400

Option A is incorrect.

B. = 288/x + 16

= 288/10.8 + 16

= 42.7

Option B is incorrect

C. = (x² ÷ 18) + 33.52

= (10.8² ÷ 18) + 33.52

= 40

Option C is correct

D. = (1,752 ÷ x) – 162/29

= (1,752 ÷ 10.8) – 162/29

= 156.6

Option D is incorrect

E. = x/12 + 36

= 10.8/12 + 36

= 36.9

Option E is incorrect

Answer:

x = 10.8

432 ÷ x = 40

(216 ÷ x) + 20 = 40

(108 ÷ x) + 30 = 40

(54 ÷ x) + 35 = 40

4. a║b                    [tex]{}[/tex]                       Corresponding angles on parallel lines are congruent

Step-by-step explanation:

The statements in the two column proof can be explained as follows;

Statement                     [tex]{}[/tex]                Explanation

1. p║q                    [tex]{}[/tex]                        Given

∠1 ≅ ∠11

2. ∠1 ≅ ∠9                     [tex]{}[/tex]               Corresponding angles on parallel lines crossed by a common transversal are congruent

3. ∠9 ≅ ∠11                    [tex]{}[/tex]               Transitive property of equality

Given that ∠1 ≅ ∠11 and we have that ∠1 ≅ ∠9, then we can transit the terms between the two expressions to get, ∠9 ≅ ∠11 which is the same as ∠11 ≅ ∠9

4. a║b                    [tex]{}[/tex]                       Corresponding angles on parallel lines are congruent

Whereby we now have ∠9 which is formed by line a and the transversal line q, is congruent to ∠11 which is formed by line b and the common transversal line q, and both ∠9 and ∠11 occupy corresponding locations on lines a and b respectively which are crossed by the transversal, line q, then lines a and b are parallel to each other or a║b.

Answer:

A frequency table shows the distribution of observations based on the options in a variable. Frequency tables are helpful to understand which options occur more or less often in the dataset. This is helpful for getting a better understanding of each variable and deciding if variables need to be recoded or not.

Step-by-step explanation:

hope this helps! :)

The usage of frequency table is to create graphs such as histograms, bar charts, and pie charts to visualize the data.

We are given that;

The frequency table

Now,

A frequency table is a table that lists items and shows the number of times the items occur. It is a way of organizing data and summarizing how often each value or category appears in a dataset.

Frequency tables can be used for any type of variable, such as categorical, ordinal, or numerical.

Frequency tables can help us to understand the distribution of data, identify patterns, and compare different groups.

For example, suppose we have a dataset of 20 students' favorite colors. We can make a frequency table to show how many students prefer each color:

| Color | Frequency |

| ----- | ---------    |

| Red   | 5         |

| Blue  | 7         |

| Green | 4       |

| Yellow| 2       |

| Pink  | 2         |

Therefore, by the table answer will be to create graphs such as histograms, bar charts, and pie charts to visualize the data.

Answer:

what ever the 5th number was -30

Step-by-step explanation:

its subtracting 30 each step

Answer:

2nd number = 13

First number = 15

3rd number = 30

Step-by-step explanation:

Let

2nd number = 1/2x - 2

First number = 1/2x

3rd number = x

Total = 58

x + 1/2x + 1/2x - 2 = 58

x + x+x/2 = 58 + 2

x + 2/2x = 60

x + x = 60

2x = 60

x = 60/2

= 30

x = 30

2nd number = 1/2x - 2

= 1/2*30 - 2

= 15 - 2

= 13

First number = 1/2x

= 1/2*30

= 15

3rd number = x

= 30

Step-by-step explanation:

2 < (-2x + 4) and (-2x + 4) > -14

Answer:

The senior class will have 100 members in the 13th year.

Step-by-step explanation:

Use the compound interest equation with a negative interest rate:

A = P(1  + r/n)^(n)(t)

Let n be 1 since we're looking for a specific year.

100 = 250(1 - 0.07)^t

100/250 = (0.93)^t

0.4 = (0.93)^t

t = 13 years

Answer:

[tex]y = 180 - 2x[/tex]

Step-by-step explanation:

Required

Triangle: Isosceles

Required

An expression for the third side

Let the equal sides be x and the third side be y

From triangle sum theorem, we have the following expression:

[tex]x + x + y = 180[/tex]

[tex]2x + y = 180[/tex]

Subtract 2x from both sides

[tex]-2x +2x + y = 180 - 2x[/tex]

[tex]y = 180 - 2x[/tex]

Hence, the third side of an isosceles triangle is: [tex]y = 180 - 2x[/tex]
