The coordinates of figure PQRS and its image P'Q'R'S' are written below. P(2,2) Q(5,2) R(5,6) S (2,6). P'(-6,2) Q'(-3,2), R' (-3,6) S(-6,6) Which single transformation can map figure PQRS onto figure P'Q'R'S'?
Answer:
A reflection across the Y-axis
Step-by-step explanation:
The single transformation can map figure PQRS onto image P'Q'R'S' is a reflection.
Given that, the coordinates of figure PQRS are P(2,2) Q(5,2) R(5,6) and S (2,6) and the coordinates of the image P'Q'R'S' are P'(-6,2) Q'(-3,2), R'(-3,6) and S' (-6,6).
What is transformation?A point, line, 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.
Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.
The figure PQRS is reflected on the y-axis and translated left to 1 unit.
Therefore, the single transformation can map figure PQRS onto image P'Q'R'S' is a reflection.

The measure of G is six more than twice the measure of H. If G and H are supplementary angles, find the measure of H pls I need help pls
Answer:
G=2H+6. -(1)
Also, G and H are supplementary angles which mean their sum would be180.
G+H=180
G=180-H. -(2)
From (1)&(2)
2H+6=180-H

solve for x graph the solution on a number line 13+15+18+x/4 <21
Hey there!
ANSWER: [tex]x<-100[/tex]EXPLANATION:[tex]13+15+18+\frac{x}{4} <21[/tex]
To get x, simplify both sides of the inequality.
[tex]\frac{1}{4}x+46<21[/tex]
Now we have to minus(subtract) 46 from both sides.
[tex]\frac{1}{4}x+46-46<21-46\\ =\frac{1}{4}x<-25[/tex]
In the last step, we'll have to multiply both sides by 4.
[tex]4*(\frac{1}{4}x)<(4)*(-25)=x<-100(ANSWER)[/tex]

In a community garden shown to the right you want to plan a fence in a vegetable garden that is adjacent to your friends Garden you have at most 44 ft of fence and the fence must around all four sides of your garden what is the possible lengths of your garden
Answer:
Length of the garden = 13 ft
Width of the garden = 9 ft
Step-by-step explanation:
Let the length of my new garden = l ft
It's given in the question,
width of the garden = 9 ft
Formula to calculate the perimeter of a rectangle is,
P = 2(L + W)
Where L = length of the garden
W = width of the garden
P = perimeter of the garden
Length of the fence = 44 ft
By substituting values in the formula,
44 = 2(l + 9)
22 = l + 9
l = 22 - 9
l = 13 ft
Therefore, length of my new garden = 13 ft
Width of the garden = 9 ft
Markus decides to return 4 shirts costing $19 each to a clothing store. While there, he decides to purchase 2 pairs of shoes at $45 each and a raincoat for $62.75. The clerk charges him 5% tax on the amount due after returns. What amount does he owe the clerk?
Answer:
$80.59
Step-by-step explanation:
You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.

what is the perimeter of a rectangle with a length of (x^2+x) and a width of (2x^2+3x)
Answer:
Perimeter = 6x² + 8x
Step-by-step explanation:
Perimeter = 2(length + width)
perimeter = 2((x²+x)+(2x²+3x))
perimeter = 2(x²+2x² + x+3x)
perimeter = 2(3x² + 4x)
perimeter = 2*3x² + 2*4x
perimeter = 6x² + 8x
What are some examples of Adjacent Congruent Angles.
Answer:
base angles of an isosceles triangleangles at successive corners of any regular polygonangles either side of an angle bisectorangles made by a perpendicular to a line (excluding vertical angles)Step-by-step explanation:
When it comes to angles, the term "adjacent" means different things in different contexts. Any pair of angles in a triangle are considered to be adjacent. The base angles of an isosceles triangle are adjacent congruent angles.
Angles at successive corners of any regular polygon are congruent adjacent angles.
Angle that have a common vertex and a common side are also called adjacent angles. Angles on either side of an angle bisector are adjacent congruent angles. Likewise any non-vertical pair of angles where lines cross at right angles are adjacent congruent angles.

Classify the system of equations and identify the number of solutions. 5x + y = 2 2y = 4 − 10x
infinitive
Step-by-step explanation:
The system of equations represents the dependent because the solution to the system of equations has infinitely many solutions.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The system of equations are:
5x + y = 2
2y = 4 − 10x
The system of equations can be written as:
5x + y = 2 ..(I)
10x + 2y = 4 ...(II)
In equation (II) divide by 2
5x + y = 2 ..(III)
Equations (I) and (III) represent the same equation:
The system of equations represents the Dependent because the solution to the system of equations has infinitely many solutions.
Thus, the system of equations represents the dependent because the solution to the system of equations has infinitely many solutions.
