Transformation involves changing the position of a point.

The image of D after the transformation is (-4,-2)

The point is given as:

[tex]\mathbf{D = (-2,-4)}[/tex]

The rule of 270 degrees counterclockwise rotation is:

[tex]\mathbf{(x,y) \to (y,-x)}[/tex]

So, we have:

[tex]\mathbf{D' = (-4,2)}[/tex]

The rule of reflection across the x-axis is:

[tex]\mathbf{(x,y) \to (x,-y)}[/tex]

So, we have:

[tex]\mathbf{D" = (-4,-2)}[/tex]

Hence, the image of D after the transformation is (-4,-2)

Answer:

b. two solution its very sample

Answer:

C: No solutions.

Step-by-step explanation:

When solving an equation and it provides a false statement, it implies that there are no values that could satisfy the given equation.  Simply put, the word "equation" in itself must provide equal values on either sides of the equal sign.

“No solution” means that there is no value, not even 0, which would satisfy the equation.

Therefore, the correct answer is C: No solutions.

Answer:

yes it is correct

Step-by-step explanation:

Answer: Yes You are correct!

Step-by-step explanation:

If a number in the tenths place is greater than or equal to 5 then we round up. Ex: 1.90 would round to 2

If a number in the tenths place is less than or equal to 4 then we round down. Ex: 1.19 would round to 1

Since 8 is in the tenths place we round up. 3.81 would be 4 rounded to the nearest whole number.

Step-by-step explanation:

given,

Harry = 3yrs

Andy = 2x ( twice as old as sam )

sam = x

their sum = 27

a/q

→ 2x + x + 3 = 27

→ 3x = 27 - 3 = 24

→ x = 24/3 = 8

→ x = 8

therefore, age of sam is 8 and Andy is 16 and Harry is 3.

the equation is

2x + x + 3 = 27

hope this answer helps you..and may u have a great day ahead!

The equation formed using the information given is x + (x + 3) + 2x = 27. Sam is 6 years old. Let x be Sam's age.

According to the given information:

1. Harry is 3 years older than Sam, so Harry's age is (x + 3) years.

2. Andy is twice as old as Sam, so Andy's age is 2x years.

3. The total of their ages is 27, so we can add their ages together and set it equal to 27:

x + (x + 3) + 2x = 27

Now, let's simplify the equation:

Combine like terms:

x + x + 3 + 2x = 27

Combine the x terms:

4x + 3 = 27

Now, we want to isolate the variable x on one side, so let's move the constant term (3) to the other side of the equation by subtracting 3 from both sides:

4x = 27 - 3

4x = 24

Finally, solve for x by dividing both sides by 4:

x = 24 / 4

x = 6

So, Sam is 6 years old.

Answer:

that it

Step-by-step explanation:

The Plot of the point (1.5, −3) on the coordinate plane is represented by Red dot in the attached graph.

The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.

The cartesian coordinate plane is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is written as; (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

Given

Point: (1.5, −3)

Required to Plot the point (1.5, −3) on the coordinate plane.

The points can be rewritten as:

First of all, we know that all triangles' angles add up to 180 degrees

Here we can tell that we have one 90 degree angle and another 45 degree angle

Now, we can subtract both of these angles to then finalize that, the missing angle is equal to 45 degrees

Answer:

24 runners

Step-by-step explanation:

If 1/4 of the runners dropped out, then 1 - 1/4 or 3/4 continued on. 3/4 of 56 or 3/4 *56 is 42 runners left. Then, out of these 42, 3/7 dropped out. This means 1 - 3/7 or 4/7 of the runners remained. This means that 4/7 * 42 or 24 runners finished the race.

Answer:

The negative numbers do not have square roots. Therefore the question does not have a solution. That is where Julie made a mistake.

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

First, let's take a look at this property:

[tex] \displaystyle \large{ \sqrt{a} \sqrt{b} = \sqrt{ab} }[/tex]

This only works for a and b ≥ 0.

As for a & b < 0 which results in Imaginary Number, we have to convert in 'i' form.

We know that:-

[tex] \displaystyle \large{ i = \sqrt{ - 1} }[/tex]

Thus:

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{3} i \cdot \sqrt{12}i }[/tex]

Then we can multiply 12 & 3 in square root.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36} {i}^{2} }[/tex]

We know that:

[tex] \displaystyle \large{ {i}^{2} = - 1}[/tex]

Convert i^2 to -1

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36}( - 1) } \\ \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - \sqrt{36}}[/tex]

Then evaluate √36 which is 6.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - 6}[/tex]

Therefore the answer should be -6.

Conclusion

Julie cannot use the √a√b = √ab property first because a & b both are < 0 and the property applies for a ≥ 0, b ≥ 0.

Answer:

a = -88

Step-by-step explanation:

50−  a/ 11  =58

50 + -1/11 x a = 58

-1/11 x a + 50 = 58

Subtract 50 from both sides

-1/11 x a - 50 (-50) = 58 (-50)

Now multiply both sides by 11/-1

(11/-1) x (-1/11 x a) = (11/-1) x 8

a = -88

The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.

Since distance traveled in miles is graphed as a function of time in hours, this implies that distance is on the y-axis and time in hours is on the x-axis.

So, the slope of the graph is distance/time and its unit is miles/hour = miles per hour = mph.

This slope represents the speed of the automobile.

So an automobile going at 50 mph represent the slope of the line which is 50.

The important clue here is when they say both The girls owe the same amount so what they mean is equate both the functions  

so we get

150 - 20n = 130 - 15n

Now n gives us the number of weeks so solve for n

20n - 15n = 150 - 130

5n = 20

n = 4
