Graph y=-x-6 YOU WILL BE MARK BRAINLIEST

Answer:

Part A:

The sequence of transformation that maps triangle DEF to triangle GHI are;

1) A reflection across the y-axis (x, y) →(-x, y) and

2) A translation 6 units down, (-x, y - 6)

Part B:

1) Yes

2) The points of the triangle GHI obtained from the mapping of triangle DEF using the given transformation are corresponding therefore, the mapping proves that the two triangles are congruent

Step-by-step explanation:

Part A:

The given coordinates of the vertices of triangle DEF are;

F(-1, 5), D(-5, 2), and E(-3, 1)

The given coordinates of the vertices of triangle IHG are;

I(1, -1), H(3, -5), and G(5, -4)

Therefore, the transformation that maps ΔDEF to ΔGHI are

1) A reflection across the y-axis (x, y) →(-x, y) and

2) A translation 6 units down, (-x, y - 6)

Reflection of point F(-1, 5) across the y-axis gives → (1, 5)

Followed by a translation 6 units down gives;

(1, 5) →T(y - 6) → I(1, -1)

Reflection of point D(-5, 2) across the y-axis gives → (5, 2)

Followed by a translation 6 units down gives;

(5, 2) →T(y - 6) → G(5, -4)

Reflection of point E(-3, 1) across the y-axis gives → (3, 1)

Followed by a translation 6 units down gives;

(3, 1) →T(y - 6) → H(3, -5)

Part B:

1) Yes mapping triangle DEF onto triangle GHI proves that the two triangles are congruent

2) The points of the triangle GHI obtained from the mapping of triangle DEF are the same, therefore, the mapping proves that the two triangles are congruent

Answer:

Mia's score is 10

Step-by-step explanation:

Mia and Evette played a game in which they scored 10 points for each correct answer and lost 20 points for an incorrect answer. Mia answered 7 questions correctly and 3 questions incorrectly. What was Mia's overall score? *

We are told that:

Correct points = 10 per answer

Incorrect points = 20 per answer

Mia answered 7 questions correctly and 3 questions incorrectly.

Hence:

7 (10) + 3(20)

= 70 points - 60 points

= 10 points

Mia's score is 10

Answer:

500

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

a. Determine the unit rate for the number of laps she can run per minute.

This will be calculated as the number of minutes used divided by the number of laps which will be:

= 25 / 10

= 2.5 minutes per lap.

b. Find the constant of proportionality for this situation.

We will use the formula y = kx

where y = 25, x = 10, k = constant of proportionality.

Therefore, y = kx

25 = 10k

k = 25/10

k = 2.5

The constant of proportionality is 2.5

Answer:

Option D

Step-by-step explanation:

Cost of 4 shirts all together = $85

Model given in the picture attached will be,

x + x + x + x = 85

4x = 85

[tex]\frac{4x}{4}=\frac{85}{4}[/tex]

x = 21.25

Therefore, Option D will be the correct option.

Answer:

a is positive and b is negative

Step-by-step explanation:

a is the slope, which is positive

b is the y intercept, where x = 0 and that is negative.

Answer:

x is 8.75

Step-by-step explanation:

cross multiplying

10x = 35(2.5)

10x = 87.5

x = 8.75

Answer:

x = 9

Step-by-step explanation:

The linear pair have a sum of 180°, thus

3x + 15x + 18 = 180

18x + 18 = 180 ( subtract 18 from both sides )

18x = 162 ( divide both sides by 18 )

x = 9

Answer:

y = 1/8x + 25/8

Step-by-step explanation:

Answer:

c^2 = 9^2 + 12^2.

C = 15 Ft. (Rt. triangle).

Possible values: 9, 12, 15Ft.

The 9 and 12 Feet lengths form Isosceles triangles.

Answer:

61

Step-by-step explanation:

a triangles angles equal 180 so 180-10-19-90 = 61

Answer:

-9

Step-by-step explanation:

Since the opposite angles of both sides are congruent we know that the sides must be congruent also. Therefore, to solve for x we can set them equal to each other.

So the equation will be x+19=10, to solve we must isolate the variable.

First, subtract 19 from both sides

x+19-19=10-19

Then, simplify

x=-9

Answer:

2√6

Step-by-step explanation:

√24

√24 can be split into √8 and √3 because 8x3=24

√8 can be split into √4 and √2, and √4 equals 2.

√3 times √2 is √6

Step-by-step explanation:

Answer: x = 15

Step-by-step explanation:

Answer:

c = 12ft

Step-by-step explanation:

[tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex]

[tex]7.2^{2}[/tex] + [tex]9.6^{2}[/tex] = 144

Answer:

x=1

y=0

Step-by-step explanation:

(x-1)=-2x+2

3x-1=2

3x=3

x=1

-2(1)+2

-2+2=0

Answer:

x =1 y=0

-2x +2= x-1  (subtract 2 from both sides)

-2x= x-3 (subtract x from both sides)

-3x= -3 (divide each side by -3)

x=1

plug it in

y= (1) -1

y=0
