The transformation is called a reflection across X axis because the point (x,y) is projected from across X-axis as (x,-y).

A point, lines, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after.

transformation, refers to the object's ultimate shape and location.

This rule is represented by the reflect placed above a white x axis transformation (x, y) (–x, y).

While the x-coordinate remains the same, the y-coordinate has shifted from its initial position.

The overall description of this is (x, y) (–x, y).

The X-coordinate of a point that is reflected all across the X-axis remains constant. The Y-coordinate, on the other hand, is changed towards the opposite sign.

The transformation is called a reflection across X axis because the point (x,y) is projected from across X-axis as (x,-y).

There is 17.5 inches distance between the tee and the hole on the model.

According to the question we have been given that

length of hole#9 is = 175 yards

the scale for the model is given as = 2 inch : 20yards

We need to find the inches between the tee and the hole.

Let the length between the tee and the hole on the model be x inches

Thus the above condition can be written as

               2 inches / 20yards = x inches/175 yards

We have to solve this proportion for x we get

                       x inches = 175*2/20

                            x = 17.5 inches

Hence there is 17.5 inches distance between the tee and the hole on the model.

300 Hours will be the Interquartile range for type A batteries.

In the given question, we have 11 terms in Hours, So we get N = 11, and the formula can calculate the Median for the allotted Hours  [tex]\frac{n+1}{2}[/tex]

Since the Median is 6th term i.e.  we get Middle Quartile Q2 = 1300Hours

Q1 is the Lower quartile of the graph and the Median divides the graph into 8 equal parts. And we get the value of Q1 = 1100 Hours. Whereas, The upper quartile is the upper quarter. So, Q3 = 1400 Hours.

We have the formula to calculate the Interquartile range :

  IQR = Q3 - Q1

Putting values of Q3 and Q1 into the formula, We get :

         IQR = 1400 - 1100

         IQR = 300

Hence, the Interquartile range  IQR = 300 Hours.

The points X(6,7), Y(2,3), Z(4,1) can be plotted as given below. From the obtained graph ∠XYZ is the right angle.

The given coordinates are X(6,7), Y(2,3) and Z(4,1).

We need to classify ∠XYZ whether it is right, acute, or obtuse.

A cartesian plane or coordinate plane can be defined as a plane formed by the intersection of two coordinate axes that are perpendicular to each other. The horizontal axis is called the x-axis and the vertical one is the y-axis. These axes intersect with each other at the origin whose location is given as (0, 0). Any point on the cartesian plane is represented in the form of (x, y). Here, x is the distance of the point from the y-axis and y is the distance from the x-axis.

Now, X(6,7), Y(2,3), Z(4,1) can be plotted as given below:

All points X(6,7), Y(2,3), Z(4,1) have the positive x and y coordinates.

So, all the points X(6,7), Y(2,3) and Z(4,1) lie in the first quadrant.

From the graph, we can see at the two lines are perpendicular to each other.

So, the angle between two lines is the right angle which is 90°.

I hope this helps, Brainliest and Thanks would be very much appreciated

Answer: 1. 8 years old

2. 10 years

3. 23 years old

4. 26 years ago

Step-by-step explanation:

G=Gwen's age.

J=Julie's age.

A=Aunt Jess's age

U=Uncle Mark's age

T=twins' ages

1. G=J+2

A=U*2

J=A+U-26

T=G/3 - 2

U-10=8

U+10-10=8+10 ==> Add 10 on both sides to single out U.

U=18

A=U*2

A=18*2

A=36

J=A+U-26

J=36+18-26

J=54-26

J=28

G=J+2

G=28+2

G=30

T=G/3 - 2

T=30/3 - 2

T=10-2

T=8 ==> 8 years old

2. 8+x=18

8-8+x=18-8

x=10 years

3. U=18

18+5=23 years old

4. G=J+2

G=J*2

J*2=J+2

2J=J+2

J=2 ==> subtract J on both sides

G=2+2

G=4

a = 5 and a = 4 are the sum of both digits, of either of two two-digit numbers.

What is square number in math?

This can also be solved algebraically. Let the 2 digits be a and b, going left to right.  The number itself is then

N = 10a + b.  And it's given that a + b = 9, and a2 - ab + b2 = 21.  Substitute for b = 9 - a, combine all terms of a2 and a, and you get

3a2 - 27a + 60 = 0.  Divide by 3

a2 - 9a + 20 = 0.  Factor

(a - 5)(a - 4) = 0.  So the roots are a = 5 and a = 4.

The actual numbers N are 54 and 45.

The digits can be changed since the equations including only a and b are symmetric. (If a = 5, then b must be 4; inverse)

the given expression is (2/5 * t - 7 + 2/3 * t) - (5/6 * t + 14)

Simplifying the expression further

we get ,

[tex]= \frac{2}{5} t-7+\frac{2}{3} t-\frac{5}{6} t-14[/tex]

writing the like terms together

= t * (2/5+2/3-5/6)-7-14

taking LCM of 5,3,6 as 30 and simplifying further we get ,

= t * (12/30 + 20/30 -25/30) - 21

= t * (7/30) - 21

From the given first image, we see that it is in the first quadrant but by the second image, we see that it is now mirrored along the horizontal axis. Thus, we can say that it is reflected across the x-axis.

After reflection, across the x-axis, we see that it was translated down by 2 units.

The last transformation is that we see it is now in quadrant 3 which means it was now reflected across the y-axis.

Emily claims that a tree height of 43 inches is an outlier for the distribution.

What is the 1.5 IQR rule for outliers?

Add 1.5 to the interquartile range (IQR) (a constant used to discern outliers). The third quartile is increased by 1.5 times (IQR). Any figure above this is thought to be an outlier.

The starting and the end of the box in box plot are first and third quartile respectively.

From the given box plot it is clear that, Q₁ = 34  and Q₃ = 38

IQR = Q₃ -  Q₁

IQR = 38 - 34

IQR = 4

According to 1.5x IQR rule for outliers, all the data values lies outside the interval [ Q₁  - 1.5 × IQR , Q₃ + 1.5 × IQR ] are outliers..

Q₃ + 1.5 × IQR = 38 + 1.5(4)

Q₃ + 1.5 × IQR = 38 + 6

Q₃ + 1.5 × IQR = 44

We know that, 43<44.

Since, 43 is not greater than Q₃ + 1.5 × IQR  therefore, 43 is not an outlier and there is no evidence to support the claim.
