Answer:
A′B′ and AB are equal in length.
Step-by-step explanation:
Given that the location of the points are at A(1, 3) and B(5, 3).
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Rigid transformation are transformation that preserves the shape and size when performed. Types of rigid transformation are reflection, rotation, translation.
Hence if AB is rotated 270 degrees counterclockwise about the origin to form A′B′, both A′B′ and AB are equal in length because rotation is a rigid transformation.
If A(x,y) is rotated 270 degrees counterclockwise about the origin, it becomes A'(y,-x).
Hence if AB is rotated 270 degrees counterclockwise about the origin to form A'(3, -1), B'(3, -5)
[tex]AB=\sqrt{(5-1)^2+(3-3)^2} =4\\\\A'B'=\sqrt{(3-3)^2+(-5-(-1))^2}=4,[/tex]
you are planning a party for 12 people and you purchase 4 bags of candy.If you have a party for 21 people,how many bags of candy should you purchase
Answer:
7
Step-by-step explanation:
one bag of candy for every three people
12 ÷ 4 = 3
21 ÷ 7 = 3
Answer:
7
Step-by-step explanation:
Apply proportions:
People/bag of candy
[tex]\frac{12}{4}[/tex]
For 21 people
[tex]\frac{21}{x}[/tex]
Equal both expressions
[tex]\frac{12}{4} =\frac{21}{x}[/tex]
Solve for x:
[tex]x=21\frac{12}{4} \\x= \frac{21}{3} \\x=7[/tex]
You should purchase 7 bags of candy
Is the relation a function?{(1,5),(1,7),(3,9),(4,11)}
Answer: No
Step-by-step explanation: Multiple Y values come from the same X value, which means its not a function.
Answer:
No
Step-by-step explanation:
Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

Lauren's vet commented that her puppy gained 10% in weight since the first visit. Write an expression that could be evaluated to show the puppy's current weight. Use a variable to represent the weight of the puppy at the first visit. Write the expression in simplified form. If the puppy gains another 10% in weight from the current visit to a future visit, how much will the puppy weigh? Write an expression that could be evaluated to show the puppy's future weight. Write the expression in simplified form.
Answer: expression to show puppy's current weight = x+ 0.1x, simplified form = 1.1x
Expression that for puppy's future weight= 1.1x + 0.1(1.1x), simplified form = 1.21 x
Step-by-step explanation:
Let x= Puppy's weight in the first visit.
If it gained 10% in weight from the first visit, then his current weight = (weight in first visit)+10% of (weight in first visit)
= x+ 0.1x
i.e. expression to show puppy's current weight = x+ 0.1x
In simplified form it will be
x+ 0.1x = x(1+0.1)
=x(1.1)
=1.1 x (simplified form )
If puppy gains another 10% in weight, then its future weight = (current weight)+10% of (current weight)
= 1.1x+10% of 1.1x
= 1.1x + 0.1(1.1x)
Expression that for puppy's future weight= 1.1x + 0.1(1.1x)
= 1.1x(1+0.1)
= 1.1x(1.1)
=(1.1)²x
= 1.21x (simplified form)

2. √8 < 3 = true
3. √8 > √7 = true
4. √8 < 2 = false
5. √8 > 8 = false
6. 1 < √8 = true
Inequalities help us to compare two unequal expressions. The inequalities that are true are 1, 2, 3 and 6.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The value of √8 is equal to 2.828427, therefore, the inequalities that are true are,

A racquetball club membership costs $22.50 per month. What would a year’s membership cost?
Answer:
270 dollars for a year, so 22.50 times 12
The cost of the membership for a year will be $270.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
A racquetball club membership costs $22.50 per month.
We know that in a year, the number of months is 12.
Then the cost of the membership for a year will be given by the multiplication of the numbers 22.50 and 12.
Cost = 22.50 x 12
Cost = $270
The cost of the membership for a year will be $270.

bob claims that he can map rectangle 1 to rectangle 2 select all of the transformations or series of transformation that support his claim
Answer:
The first thing you need to notice is that each mark in the coordinate axis represents 2 units.
Now, let's analyze each option that maps rectangle 1 to rectangle 2.
Reflection over the line x = 1, and a translation of 2 units down.
You can see that the right end of rectangle 1 us located at x = -2
The distance between x = -2 and the line of reflection is:
1 - (-2) = 3
Then the left end of the reflected rectangle will e 3 units at the right of x = 1.
1 + 3 = 4
Will be at x = 4, same as rectangle 2.
Now we move it 2 units down, and we will have rectangle 1 mapped into rectangle 2.
Translation of 12 units right, and then 2 units down.
The right end of rectangle 1 is at x = -2
The right side of rectangle 2 is at x = 10
The difference is 10 -(-2) = 12
Then we must move rectangle 1 12 units to the right.
Now, same as before, we can move rectangle 1 2 units down and we will have rectangle 1 mapped into rectangle 2.
Rotation of 180° around the point (1, 4)
This means a reflection over the line x = 1, followed of a reflection over the line y = 4.
We already see that a reflection over the line x = 1 leaves rectangle 1 right above rectangle 2. And the line that separates them is the line y = 4, then when we do a reflection over that line, we will have rectangle 1 mapped into rectangle 2.
