A graph showing the transformed image
The image show a reflection over x axis, the transformation rule for this is
Transformation rule (x, y) → (x, -y)
applying the rule to f(x) = |x| gives -f(x) = -|x|
followed by translation 2 units up, this achieved by Transformation rule
-f(x) → -f(x) + 2
Then a vertical stretch of 2 units, transformation rule for vertical stretch is

1.) Ace wanted to buy a gift for his mother
worth $18.60. He has $7.40 in Savings
and another $6.30 Saved from his
allowance for the past two weeks. How much more
does he need to save this week?
Answers
Answer:
$4.90
Step-by-step explanation:
He already has $13.70 (7.40+6.30) saved up so you have to subtract that from 18.60 to find the total Ace needs to save up.
18.60-13.70=4.90
To check your answer, you can add 7.40, 6.30, and 4.90 and see if you get a total of 18.60.
Check: 7.40+6.30+4.90=18.60

The fraction of the patients that have a waiting time of more than 7 minutes found by using the area under the curve is 269/312
What is a fraction in mathematics?A fraction indicates the quantitative comparison showing the number of times one quantity is contained in another quantity.
The area under the frequency curve is found as follows;
Dividing the area into composite shapes of a rectangle, triangle and trapezoid, we get;
(9.2 - 5.5) × 4 + (4 + 2)×3/2 + (2.5 + (9.2 - 5.5)) × 1/2 + (2.5 + 1.2) × 2/2 + 1.2 × 1/2 = 31.2
The area for those that have a waiting time of more than 7 minutes is therefore;
(9.2 - 5.5) × 4 + (4 + 2)×3/2 + (2.5 + (9.2 - 5.5)) × 1/2 = 26.9
The fraction that have a waiting time of more than 7 minutes is therefore;
26.9/31.2 = 269/312 ≈ 0.862
The fraction of the patients that have a waiting time of more than 7 minutes is 269/312

9. The sum of two numbers is 130 and their difference is 34. Let x be the first number and y be the second

Answers
Using the system of equations and use the elimination method the two numbers are 82 and 48.
What is the elimination method?
To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are equal.
Here, we
let the first number = x
let the second number = y
according to the given conditions:
x + y = 130 ........(1)
x - y = 34 .........(2)
Using the elimination method we add both equations (1) and (2) and we get
2x = 164
x = 164/2 = 82
Now, we substitute the value of x in eq (1) and we get
82 + y = 130
y = 130-82
y = 48
Hence, using the system of equations and use the elimination method the two numbers are 82 and 48.

The burner is the engine of the balloon. What is the role of a resistor in an engine?
Answers
A ballast resistor is utilized inside the ignition system of automobile engines or balloons. it acts as a resistor for the ignition ballast.
Between the main source of both the ignition coil & the coil stud, there's an ignition ballast resistor. It lowers the ignition coil's risk of failure.
An ignition ballast resistance assists in lowering the coil voltage & coil current when the generator revs the engine.
Minimal current consequently results in a low-temperature increase. Additionally, the ignition coil lives a long time as a result.
However, an ignition system requires a greater voltage that is also the same as the power source's voltage. Therefore, a resistor for the ignition ballast is connected to the jumper wire. The jumper wire additionally supplies the ignition with the necessary voltage when starting the engine.

1. Kevin took $45 with him to spend on snack for himself and his friends at the movie theater. The price for each bucket of popcorn was $4. The price of each drink was half the price of a bucket of popcorn.
(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of buckets of popcorn and the other axis to represent the number of drinks.
(b) Explain your graph.
Answers
The equation of the relationship is 2x + 4y = 45 and the graph is attached
How to sketch the graph?From the question, we have the following parameters:
Amount = $45Price of each bucket of popcorn = $4Price of each drink = Half the price of each bucket of popcornThis means that
Price of each drink = Half $4
Evaluate
Price of each drink = $2
Represent the number of drinks with x and the number of bucket of popcorn with y
So, we have the following representation
Total amount of popcorn + Total amount of drinks = Total amount
This gives
2x + 4y = 45
Next, we sketch the graph
See attachment for the graph of the equation
The explanation of the graphThe graph is represented by a straight line
This means that it is a linear equation
Also, the graph touches the axes at (0, 11.25) and (22.5, 0)
This means that the highest number of drinks and buckets are 11.25 and 22.5 respectively

Using the simplification, the equivalent expression of 2.1+(–3.7h)+1.9h–1.4 is 0.7–1.8h.
In the given question we have to find the equivalent expression of the given expression.
The given expression is 2.1+(–3.7h)+1.9h–1.4
Now solving the given expression to find the equivalent expression.
Now solving the expression
=2.1 + (–3.7h) + 1.9h – 1.4
Firstly simplifying the bracket
=2.1–3.7h+ 1.9h – 1.4
=(–3.7h+ 1.9h)+(– 1.4+2.1)
= –1.8h + 0.7
We can write it as
=0.7–1.8h

A doctor wants to estimate the mean HDL cholesterol of all 20- to 29-year-old females. How many subjects are needed to estimate the mean HDL cholesterol within 4 points with 99% confidence assuming S=13.8 based on earlier studies? Suppose the doctor would be content with 90 confidence. How does the decrease in confidence affect the sample size required?
Answers
The way the decrease in confidence affect the sample size required is: A. Decreasing the confidence level decreases the sample size needed.
How to find the sample size ?Using this formula to find the decrease in sample size
n = [zs/E]^2
Where:
n = Sample size
zs = z-score
E= margin of error
Confidence coefficient for 99% = 2.58
Hence,
2.58 × 13.8/sqrt(n) = 0.04
2.598 × 13.4 /0.04 = sqrt(n)
( 2.598× 13.8 /0.04)^2 = n
n=803,371.6
So,
Confidence coefficient for 90% = 1.64
n= (1.64× 13.8/0.04)^2
n =320,129.64
Therefore the correct option is A.
