The sequence of transformations that results in quadrilateral QSRT being mapped onto quadrilateral Q'R'S'T is as follows:
1. Translation: Shift the quadrilateral QSRT two units to the left and four units down to align point Q with point Q'.
2. Reflection: Reflect the translated quadrilateral over the line y = -6 to flip it horizontally.
3. Translation: Shift the reflected quadrilateral eight units to the right to align point S with point S'.
4. Reflection: Reflect the translated quadrilateral over the line y = -4 to flip it vertically.
Therefore, the sequence of transformations is: Translation, Reflection, Translation, Reflection.

Becky and Luke bought the same kind of pencils and erasers. Becky spent $1.45
for 2 pencils and 3 erasers. luke spent $ 2.65 for 5 pencils and 1 eraser.
What is the cost of 1 eraser
for 2 pencils and 3 erasers. luke spent $ 2.65 for 5 pencils and 1 eraser.
What is the cost of 1 eraser
Let's denote the cost of 1 pencil as x and the cost of 1 eraser as y.
From the information given, we can create the following system of equations based on the amounts spent by Becky and Luke:
2x + 3y = 1.45
5x + y = 2.65
Now, we can solve this system of equations to find the values of x and y.
First, we can rewrite the second equation as y = 2.65 - 5x and substitute this into the first equation:
2x + 3(2.65 - 5x) = 1.45
2x + 7.95 - 15x = 1.45
7.95 - 13x = 1.45
-13x = -6.5
x = 0.5
Now that we have found the cost of 1 pencil (x = $0.5), we can substitute this back into the second equation to find the cost of 1 eraser:
5(0.5) + y = 2.65
2.5 + y = 2.65
y = 2.65 - 2.5
y = 0.15
Therefore, the cost of 1 eraser is $0.15.

Now, we can solve this system of equations to find the values of x and y.
First, we can rewrite the second equation as y = 2.65 - 5x and substitute this into the first equation:
2x + 3(2.65 - 5x) = 1.45
2x + 7.95 - 15x = 1.45
7.95 - 13x = 1.45
-13x = -6.5
x = 0.5
Now that we have found the cost of 1 pencil (x = $0.5), we can substitute this back into the second equation to find the cost of 1 eraser:
5(0.5) + y = 2.65
2.5 + y = 2.65
y = 2.65 - 2.5
y = 0.15
Therefore, the cost of 1 eraser is $0.15.
Which sets of ordered pairs represent a function? Select all that apply.

D(1,4),(2,4),(1,3),(2,3)
E(1,4),(2,2),(3,1),(4,3)
A function is a relation where each input value (x) is associated with exactly one output value (y). This means that for each x, there cannot be multiple y values.
Let's analyze the ordered pairs given in each set:
A(1,1),(1,2),(1,3),(1,4) - This set is not a function because the input value 1 is associated with multiple output values (1, 2, 3, 4).
B(1,1),(2,2),(3,3),(4,4) - This set represents a function because each input value is associated with only one output value.
C(1,1),(2,1),(3,1)(4,1) - This set is a function because each input value is associated with only one output value.
D(1,4),(2,4),(1,3),(2,3) - This set is not a function because the input values 1 and 2 are associated with multiple output values (1→4, 3 and 2→4, 3).
E(1,4),(2,2),(3,1),(4,3) - This set is a function because each input value is associated with only one output value.
Therefore, the sets that represent functions are B, C, and E.

Enter your answer in the space provided.
a linear function to represent the total cost, Ya new customer would pay for X months of service.
Enter your answer in the space provided.
The linear function to represent the total cost (Y) a new customer would pay for X months of phone service can be expressed as:
Y = 35X + 20
In this function, 35X represents the cost of the monthly phone service for X months, and the fixed cost of $20 is added for opening a new account.
Y = 35X + 20
In this function, 35X represents the cost of the monthly phone service for X months, and the fixed cost of $20 is added for opening a new account.
