Angles are

No sean was wrong

Answer:

Sean is not correct. The answers are 100°, 35° and 45°.

Step-by-step explanation:

In my working, I labeled the part without a variable as a°.

Step 1: a° + 80° = 180° ( angles on a straight line sum up to 180° )

Step 2: a° = 180° - 80°. This is because 80 moves from the left side of the equation to the right side of the equation which affects it's sign( from + to -)

Step 3: a° = 100° . Subtract 80 from 180.

So we know that 100 is correct. Let's find the remaining angles.

Step 4: a° + ( x - 5 )° + ( x + 5 )° = 180° ( angles in a triangle sum up to 180°)

Step 5: 100° + x - 5° + x + 5° = 180°. Fix in the values of each variable correctly. Here we only know the value of variable a.

Step 6: (100° - 5° + 5°) + (x + x) = 180°. Group like terms to make calculations easier.

Step 7: 100° + 2x = 180°. -5+5 is the same as 5-5 which would give you 0. 0 + 100° is 100°.

Step 8: 2x = 180° - 100°. Move like terms to one side.

Step 9: 2x= 80°. Subtract 100° from 180° to get 80°

Step 10: 2x/2 = 80°/ 2. Divide both sides by 2.

Step 11: x= 40°. But this isn't the final answer. This is just the answer for all the x you see in the diagram. So fix in the values correctly.

Step 12: ( x-5° ). State it for your teacher to know which question you are given an answer to. From our calculations, we know that x = 40°.

Step 13: (40° - 5°)

Step 14: ( 35°). 40 minus 5 is 35.

Step 15: 35°. multiply the figure in the bracket by one. We can't leave our answer in the bracket.

Step 16: (x + 5). Using the same knowledge, fix in the values and do as the operation sign says.

Step 17: ( 40° + 5 °)

Step 18: (45°)

Step 19: 45 °

Step 20: Sean is not right because the angles in the triangle are 100°, 35° and 40°.

This is called ASA

Answer:

ASA postulate

Answer C is correct

Step-by-step explanation:

<ACB = < BED (Angle)

AC = DE (Side)

<CAB = < BED = 90° (Angle)

Therefore,

ABC triangle is congruent to DBE triangle according to ASA postulate.

Answer:

f(x) = 8x

Step-by-step explanation:

The linear equation given in the form of a table is shown as:

[tex]\left[\begin{array}{ccc}x&f(x)\\3&24\\4&32\\5&40\\6&48\end{array}\right][/tex]

Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):

24 ÷ 3 = 8

32 ÷ 4 = 8

40 ÷ 5 = 8

48 ÷ 6 = 8

Because the quotient for each relation is 8, the linear equation can be written as f(x) = 8x.

Answer:

12 - x= 3

x + 3y = 27

4y + 10 = 34

1/3xy = 18

Step-by-step explanation:

evaluating where x = 9 and y = 6

12 - x

12 - 9 = 3

x + 3y

9 + 3(6) = 9 + 18 = 27

4y + 10

4(6) + 10 = 24 + 10 = 34

1/3xy

1/3(9* 6 ) = 54 / 3 = 18

The values of the expressions are given below:-

12 - x= 3

x + 3y = 27

4y + 10 = 34

1/3xy = 18

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Evaluating where x = 9 and y = 6

1) 12 - x

12 - 9 = 3

2) x + 3y

9 + 3(6) = 9 + 18 = 27

3) 4y + 10

4(6) + 10 = 24 + 10 = 34

4) 1/3xy

1/3(9* 6 ) = 54 / 3 = 18

Therefore, the values of the different expressions are solved above.

The domain of a function is the set of input values, the function can take.

The domain of the function is: [tex]\mathbf{(-\infty,\infty)}[/tex]

The function is given as:

[tex]\mathbf{f(x) = \frac{1}{25}\big(\left|6x\right|+4x\big)}[/tex]

The above function represents the number of steps she runs or up down from her current position.

Because she can move in either directions (i.e. up or down), then it means that, the domain of the function is: [tex]\mathbf{(-\infty,\infty)}[/tex]

200S+500W≤$100,000 inequality to describe the constraints and (200, 100) is one solution to the inequality.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

Given,

A farmer is creating a budget for planting soybeans and wheat.

Planting soybeans costs $200 per acre and planting wheat costs $500 per acre.

Let S be the acre of land to plant soyabean  and W be the acre of land to plant wheat.

200S+500W≤$100,000

This is the required inequality.

(200,100) is the solution of inequality.

Hence 200S+500W≤$100,000 inequality to describe the constraints and (200, 100) is one solution to the inequality.
