(x,y) → (-x,y - 9) is the correct transformation for the given graph so option (A) will be correct.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

Given the quadrilateral QRST not if we look at Q'R'S'T' it is 9 units downward so it means there will be 9 units decrement in y units.

So y → y - 9

Now,

Q'R'S'T' is as far from the x-axis as QRST but on the negative x-axis.

So,

x → -x

Hence "(x,y) → (-x,y - 9) is the correct transformation for the given graph".

Answer:

x=115/2

Step-by-step explanation:

Answer:

x = 57.5

Step-by-step explanation:

Step 1: Write equation

2x + 65 = 180

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

2(115/2) + 65 = 180

115 + 65 = 180

180 = 180

LCM is 30.

Step-by-step explanation:

She forgot that they both can multiply into 30. She listed all their multiples and their LCM is 30. Not 60. That's her error.

Answer: x=15/19 =0.789

Step-by-step explanation:  -12*x+1-(7*x-14)=0

  -19x+15 = 0  

Subtract  15  from both sides of the equation :  

                     -19x = -15

Multiply both sides of the equation by (-1) :  19x = 15

Divide both sides of the equation by 19:

                    x = 15/19 = 0.789

x = 15/19 = 0.789

Hello.

Vertical angles are two sets of angles congruent to each other, both on opposite sides, but measure the same.

In the diagram shown, both angles ∠BFC and ∠EFA are identical, it seems mirrored, thus they are vertical angles.

The correct answer is B.

Answer: x=40

Step-by-step explanation:Let's solve your equation step-by-step.

6+0.5x=26

Step 1: Simplify both sides of the equation.

0.5x+6=26

Step 2: Subtract 6 from both sides.

0.5x+6−6=26−6

0.5x=20

Step 3: Divide both sides by 0.5.

0.5x

0.5

=

Answer:

7.92

Step-by-step explanation:

Given

c² + 0.1c - 24 ← substitute c = - 5.7 into the expression

= (- 5.7)² + 0.1(- 5.7) - 24

= 32.49 - 0.57 - 24

= 31.92 - 24

= 7.92

Answer:

14 + 22 = 36

Step-by-step explanation:

well last time i checked the answer is pretty clear

150 ÷ 20 = 7.5 minutes per 1 mile

7.5 x 6 = 45 minutes

7.5 + 7.5 = 15 minutes or 2 miles in 15

60 ÷ 7.5 = 8 mph

mpm = 7.5

90 ÷ 5 = $18 per hour

18 x 8 = $144

18 x 3 = 54 (close to $60)

              (e) 7.5 minutes per mile          (f)  $144         (g) 3 1/3 hours

Step-by-step explanation:

[tex]\text{Joey:}\quad \dfrac{\$11}{3\ hours}\\\\\\\text{Sarah:}\quad \dfrac{\$2}{\frac{1}{2}\ hour}\times \dfrac{6}{6}=\dfrac{\$12}{3\ hours}[/tex]

Answer:

0.25m³

Step-by-step explanation:

If Riya is applying mulch to her garden. She applies it at a rate of 250,000 cm³ for every m², to know how much she is applying in m³ for every m², we will make use of the conversion formula:

100cm = 1m

1cm = 1/100m

1cm = 0.01m

250,000cm³ = 250,000 × 1cm×1cm×1cm

250,000cm³ = 250,000×0.01×0.01×0.01

= 250,000×0.000001

= 0.25m³

Hence Riya is applying at 0.25m³ per m²

Answer:

0.25m³ / m²

Step-by-step explanation:

Given that:

Rate of application = 250,000 cm³ of mulch per m²

The rate of application in m³ per m² can be calculated thus :

Converting 250,000 cm³ to m³

1cm = 1/100 = 0.01m = 1 * 10^-2 m

Hence

1cm³ = (1 * 10^-2 m)³ = 1 × 10^-6 m³

Hence,

250,000cm³ = (250,000 * 10^-6)m³ = 0.25m³

Hence, rate of application in m³ / m² equals

0.25m³ / m²

Answer:216

Step-by-step explanation:3x9x8

Answer:

12

Step-by-step explanation:

Step-by-step explanation:

-10x - y = 27 ...1

-4x - y = 9 ...2

...1 - ...2

-10x -y - (-4x - y) = 27 - 9

-10x -y +4x + y = 18

-10x + 4x = 18

-6x = 18

x = 18/(-6)

= -3

Answer:

x = - 3, y = 3

Step-by-step explanation:

Given the 2 equations

- 10x - y = 27 → (1)

- 4x - y = 9 → (2)

Multiplying (1) by - 1 and adding to (2) eliminates the term in y

10x + y = - 27 → (3)

Add (2) and (3) term by term to eliminate y

6x = - 18 ( divide both sides by 6 )

x = - 3

Substitute x = - 3 into either of the 2 equations and solve for y

Substituting into (2)

- 4(- 3) - y = 9

12 - y = 9 ( subtract 12 from both sides )

- y = - 3 ( multiply both sides by - 1 )

y = 3

Solution is x = - 3, y = 3

Answer:

Eric earnings equals $7

Step-by-step explanation:

Let amount earned by Robert = $10

Amount earned by Eric = $x

Robert earnings = 2x - 4

2x - 4 = 10

2x = 10 + 4

2x = 14

Divide both sides by 2

x = 14 / 2

= 7

x = 7

Eric earns $x which is equal to $7

Eric earnings equals $7

Given:

The expression is [tex]\dfrac{7}{\frac{5}{8}}[/tex].

To find:

The shows the correct way to use the rule ""multiply by the reciprocal"" for the given expression.

Solution:

According to the rule "multiply by the reciprocal", if a,b,c,d are four number, then

[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

We have,

[tex]\dfrac{7}{\frac{5}{8}}[/tex]

It can be written as

[tex]\dfrac{7}{\frac{5}{8}}=\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}[/tex]

Using the rule "multiply by the reciprocal", we get

[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7}{1}\times \dfrac{8}{5}[/tex]

[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7\times 8}{1\times 5}[/tex]

[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{56}{5}[/tex]

Therefore, the correct option is D.

Answer:

6x-18

x=-3

Step-by-step explanation:

Answer:

P = 2( l + b )

=>130 = 2 (l + 30)

=>130 = 2l + 2*60

=> 130 = 2l + 60

=> 130 - 60 = 2l

=> 70 = 2l

=> 70/2 = l

=> 35 = l

Length = 35cm

Area = l * b

=> A = 35 * 30

=> A = 1050

Therefore area = 1050[tex]cm^{2}[/tex]
