Answer:

A

Step-by-step explanation:

Points of origin are  (-3,0) and (0,1). Now we determine if it is a positive slope, it is as it goes up not down. It goes up 1 unit and over to the right 3 units, making the slope 1/3.

Answer:

23. because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.

Answer:

2631 divided by 24 = 109.625

Step-by-step explanation:

The result of 2631/24 is a terminating decimal with 3 digits to the right of the decimal point.

2631 divided by 24 in decimal = 109.625

2631 divided by 24 in fraction = 2631/24

2631 divided by 24 in percentage = 10962.5%

Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 2631 and 24, of course.

Repetends, if any, are denoted in ().

The conversion is done automatically once the nominator, e.g. 2631, and the denominator, e.g. 24, have been inserted.

SPANISH:

El resultado de 2631/24 es un decimal final con 3 dígitos a la derecha del punto decimal.

2631 dividido por 24 en decimal = 109,625

2631 dividido por 24 en fracción = 2631/24

2631 dividido por 24 en porcentaje = 10962,5%

Tenga en cuenta que puede utilizar nuestra calculadora de última generación anterior para obtener el cociente de dos enteros o decimales cualesquiera, incluidos 2631 y 24, por supuesto.

Los repetends, si los hay, se indican en ().

La conversión se realiza automáticamente una vez que el nominador, por ejemplo, 2631, y el denominador,

Answer:

D and E

Step-by-step explanation:

D) Δ ABC  , ΔDCB

AB = DC

BC = CB

AC =  DB

Side Side Side congruent.

E)Δ ABC  , ΔDCB

AB = DC

∠D = ∠A

AC = DB

Side Angle Side congruent.

Answer:

E

Step-by-step explanation:

When we write that 2 triangles are congruent we have to write the letters in order of their corresponding sides so ΔABC has the sides in order

AB, then BC, and then CA

the corresponding sides of the other triangle are

DC, then CB, then BD so the other triangle should be Δ DCB

because (AB≅DC, BC≅CB, CA≅BD)

In this case we eliminate the A,B,C answers.

D is also not correct because we do not know if <ABC is congruent with <DCB

E is correct because we are given the sides AB≅DC, and  CA≅BD and we know that  BC≅CB because of the reflexive property (a line segment is congruent with itself).

We have 3 ≅sides so we can use the Side-Side-Side Congruence Theorem

F is not correct because we have enough information.

Answer:

6x-1

Step-by-step explanation:

13 + 2(3x − 7)

Distribute

13 + 6x -14

Combine like terms

6x+13-14

6x-1

Answer:

6x - 1

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

Since the triangles are similar then corresponding sides are in proportion, that is

[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{7x}{7}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )

7x² = 28 ( divide both sides by 7 )

x² = 4 ( take square root of both sides )

x = [tex]\sqrt{4}[/tex] = 2

Answer:

B

Step-by-step explanation:

Perimeter is the sum of all the lengths of its sides.

Perimeter of the figure

= 9x +8x -2 +17x -6 +5x +1

= 9x +8x +17x +5x -2 -6 +1

= 39x -7

Thus, the correct answer is option B.

Answer:

100

Step-by-step explanation:

angles CHF and EHI are congruent angles because CD is a straight line.

Therefore EHI must be 20 degrees.

angles DIG and EIH are congruent angles because CD is a straight line.

Therefore EIH must be 60 degrees.

Now that you know two of the three angles in the triangle HEI,

Total degrees in a triangle - EIH - EHI = HEI

180 - 60 - 20 = 100

Answer:

Step-by-step explanation:

smallest is X

middle is X+1

largest is X+2

2X = x+2 + 17

2X = x + 19

x = 19

19. 20, 21

Answer:

40° and 50°

Step-by-step explanation:

90=(x+10)+x

90=2x+10

80=2x

40=x

Therefore the answer is,

40 and 40+10

40° and 50°

Answer:

50° and 40°

Step-by-step explanation:

Complementary angles sum to 90°

let one angle be x then the other is x - 10

x + x - 10 = 90

2x - 10 = 90 ( add 10 to both sides )

2x = 100 ( divide both sides by 2 )

x = 50

x - 10 = 50 - 10 = 40

The angle measures are 50° and 40°

Answer:

3 terms

Step-by-step explanation:

2x² - 3y + 5

The 3 terms are 2x² , - 3y and + 5

Answer:  b = 3

Step-by-step explanation:

9 − 27 = 3(2 − 8) + 2

9 − 27 = 6 − 24 + 2

9 − 27 = 6 − 24+ 2

9 − 27 = 8 − 24

9−27=8−24

9−27+27=8−24+27

9 = 8 + 3 ------Subtract 8b from both sides

b = 3
