What is a transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given that, the square with vertices (-1, 2), (-1, -2), (3, -2) and (3, 2).
(1) Reflection over the y-axis
Then the vertices become (1, 2), (1, -2), (-3, -2) and (-3, 2)
So, the transformation carries the square onto itself.
(2) Reflection over the x-axis
Then the vertices become (-1, -2), (-1, -2), (3, 2) and (3, -2)
So, the transformation carries the square onto itself.
(3) Rotation of 180 degree around point (1, 0)
(x, y) becomes (-y, x) 180° clockwise
So, the coordinate points are (-2, -1), (2, -1), (2, 3) and (-2, 3)
So, the transformation does not carries the square onto itself.

?
Answer:
y = (2/3)x + 3
Step-by-step explanation:
first we need to find the y-intercept
we can do this by using what is given, the point (-3,1) and the slope (2/3)
using the slope-intercept formula: y = mx + b.
m = slope
b = y intercept
we can plug in the x and y values we were given
so,
1 = (2/3)(-3) + b
we can now easily solve for b
1 = (2/3)(-3) = b
first multiply
1 = -2 + b
then add 2 to both sides, this way we isolate b
3 = b
now that we have the y intercept we can write the equation of the line
y = (2/3)x + 3
if you really wanted to, you can check if this is correct by plugging in the point again and seeing if the equation is true.
1 = (2/3)(-3) + 3
multiply first
1 = -2 + 3
add the like terms

a plane left kennedy airport on tuesday morning for a 595-mile, 5-hour trip. for the first part of the trip, the average speed was 110 mph. for the remainder of the trip, the average speed was 125 mph. how long did the plane fly at each speed? first part of trip h second part of trip h
The plane flew at 110 mph for 4.55 hours and at 125 mph for 0.45 hours.
The first step in solving this problem is to recognize that we can use the formula
=> speed = distance/time
to find the time it took for the plane to travel at each speed. Let's denote the time the plane traveled at the first speed (110 mph) as t1, and the time it traveled at the second speed (125 mph) as t2.
We know that the total distance traveled was 595 miles, and the total time taken was 5 hours. Using the formula for average speed, we can write:
Average speed = total distance / total time
Therefore,
Average speed = 595 / 5 = 119 mph
Now we can use the information about the two speeds to set up a system of equations. The first equation relates the total distance traveled at the first speed to the time it took:
110t₁ = d₁
where d1 is the distance traveled at the first speed. Similarly, the second equation relates the total distance traveled at the second speed to the time it took:
125t₂ = d₂
where d₂ is the distance traveled at the second speed.
The total time taken is the sum of the times taken at each speed:
t₁ + t₂ = 5
We now have three equations and three unknowns (t₁, t₂, and d₂). We can use the first two equations to eliminate d₁ and d₂, and then solve for t₁ and t₂.
Multiplying the first equation by 125/110, we get:
125/110 * 110t₁ = 125/110 * d₁
125t₁/110 = d₂
Substituting d₂ in the third equation, we get:
t₁ + 125t₁/110 = 5
Multiplying both sides by 110, we get:
121t₁ = 550
Solving for t₁, we get:
t₁ = 4.55 hours
Substituting t₁ in the third equation, we get:
t₂ = 0.45 hours
Therefore, the plane flew at 110 mph for 4.55 hours and at 125 mph for 0.45 hours.

The number in a bacteria lab can be modeled by the function L(t)= 880(3)^t+2. Write an equivalent function in the form L(t)= ab^t
The equivalent function to the given one is:
L(t) = 7,920*(3)^t
How to rewrite the function?Here we want to rewrite the function:
L(t) = 880*(3)^(t + 2)
Into the form:
L(t) = a*(b)^t
Remember the rule for exponents:
(x^a)*(x^b) = x^(a + b)
Then we can take our function:
L(t) = 880*(3)^(t + 2)
And rewrite this as:
L(t) = 880*(3^t)*(3^2)
L(t) = 9*880*3^t
L(t) = 7,920*(3)^t

Then they sold half of the puppies that were left in the litter and half a puppy to the poodle palace. Then they decided to give the one remaining puppy to their friend Grace. How many puppies were originally in the litter
There were originally 10 puppies in the litter, as of the given condition.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
We can represent the number of original puppies as "x", and the sequence of events can be represented as:
Sold half of the puppies, so they have x/2 left - 1 sold to the local pet shop.
Sold half of the remaining puppies, so they have (x/2 - 1)/2 left sold to poodle palace.
One puppy was given to Grace, so they have ((x/2 - 1)/2- 1 = x - 2 / 4 - 1 remaining.
Since they are left with x - 2 / 4 - 1 puppies in the end, we can set this equal to 1 (the remaining puppy given to Grace), and solve for x:
x - 2 / 4 - 1 = 1
x - 2 = {1 + 1} * 4
x = 8 + 2
x = 10

what value represents the number of ways in which the expected classes are free to vary in the chi‑square goodness‑of‑fit test?
In the chi-square goodness-of-fit test, the number of ways in which the expected classes are free to vary is represented by the degrees of freedom (df) of the test.
The degrees of freedom for the chi-square goodness-of-fit test are calculated as df = k - 1, where k is the number of categories or classes being compared.
In this test, we compare the observed frequencies in each category with the expected frequencies, assuming that the null hypothesis is true. The null hypothesis is that there is no significant difference between the observed and expected frequencies, and any deviation between the two is due to chance.
The degrees of freedom are the reflection of the number of independent pieces of information that are available to estimate the expected frequencies.
The more degrees of freedom, the more likely it is that the observed frequencies could be due to chance, and the less significant the test result will be. Conversely, fewer degrees of freedom means that the observed frequencies are more likely to be significantly different from the expected frequencies, and the test result will be more significant.

Given that the function is f(x) = [tex]\frac{x-7}{x+4}[/tex]
Change f(x) (or whatever the function name is) to "y". In this case you'd get:
y = [tex]\frac{x-7}{x+4}[/tex]
Now, switch x and y. Wherever you see y, put x. And wherever you see x, put y.

. if these particular light bulbs have a mean lifetime of 2 months with a standard deviation of 0.25 months (per the manufacturer), determine the probability that this box of 40 lightbulbs will last for 5 years.
The probability that a box of 40 light bulbs will last for 5 years is very low, due to the short mean lifetime of 2 months and the relatively high standard deviation of 0.25 months.
The mean lifetime of a particular type of light bulb is given as 2 months, and the standard deviation is given as 0.25 months. The mean lifetime represents the average time that the light bulbs will last, while the standard deviation represents how much the lifetimes of the bulbs vary from the mean.
To determine the probability that a box of 40 light bulbs will last for 5 years, we need to convert the given information into a format that we can work with. 5 years is equal to 60 months, and since we have 40 light bulbs, we can assume that the lifetimes of the bulbs are independent and identically distributed. This means that the probability of one bulb lasting for 60 months is the same as the probability of any other bulb lasting for 60 months.
Next, we need to calculate the standard deviation of the sample mean. The standard deviation of the sample mean represents how much the means of different samples of size 40 would vary from the population mean. The formula for the standard deviation of the sample mean is given by the following equation:
standard deviation of the sample mean = standard deviation of the population / square root of the sample size
In this case, the standard deviation of the population is given as 0.25 months, and the sample size is 40. Therefore, the standard deviation of the sample mean is:
0.25 / sqrt(40) = 0.0395
Now that we have the mean lifetime and the standard deviation of the sample mean, we can use the normal distribution to determine the probability that a box of 40 light bulbs will last for 5 years. We can assume that the lifetimes of the bulbs follow a normal distribution with a mean of 2 months and a standard deviation of 0.0395 months (which is the standard deviation of the sample mean).
To find the probability that a bulb will last for 60 months, we can use the following equation:
z = (x - μ) / σ
where z is the standard score, x is the value we want to find the probability for (60 months in this case), μ is the mean, and σ is the standard deviation.
Plugging in the values, we get:
z = (60 - 2) / 0.0395 = 1509.49
To find the probability corresponding to this standard score, we can use a standard normal distribution table or a calculator. The probability is extremely small (close to zero), which means that it is highly unlikely that all 40 light bulbs will last for 5 years.

a family has two cars. during one particular week, the first car consumed gallons of gas and the second consumed gallons of gas. the two cars drove a combined total of miles, and the sum of their fuel efficiencies was miles per gallon. what were the fuel efficiencies of each of the cars that week?
Quadratic equation gives us the fuel efficiencies of the two cars for the given values of fuel consumption and total distance driven.
Let's denote the fuel efficiency of the first car as x miles per gallon, and the fuel efficiency of the second car as y miles per gallon.
We know that the first car consumed a total of a gallons of gas, and the second car consumed b gallons of gas. If we assume that the fuel efficiencies are constant, then the total distance driven by both cars can be calculated using the formula:
distance = fuel consumed / fuel efficiency
So, the total distance driven by both cars is:
(a/x) + (b/y) = total miles
We also know that the sum of their fuel efficiencies was:
x + y = total miles per gallon
We have two equations and two unknowns, so we can solve for x and y. First, we can solve the second equation for x:
x = total miles per gallon - y
Substituting this expression for x into the first equation, we get:
(a / (total miles per gallon - y)) + (b / y) = total miles
Multiplying both sides by y(total miles per gallon - y) to eliminate the denominators, we get:
ay + b(total miles per gallon - y) = total miles * y(total miles per gallon - y)
Expanding the left side and simplifying, we get a quadratic equation in y:
(total miles^2 - a - b) y^2 + (total miles * a) y - ab = 0
Using the quadratic formula, we can solve for y:
y = [(total miles * a) ± sqrt((total miles * a)^2 + 4ab(total miles^2 - a - b))] / 2(total miles^2 - a - b)
We can then use the equation x = total miles per gallon - y to find the value of x. The gives the fuel consumption of both cars.
