Step-by-step explanation:
Given the system of equations:
2x + 3y = 15
X + 3y = 0
What is x?
2x + 3y = 15
X + 3y = 0 subtract the bottom equation fron the top one
2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero
2x - x = 15
x = 15 Now for extra credit what is y?
X + 3y = 0
15 + 3y = 0
15 - 15 + 3y = 0 - 15

Triangle ABC is translated by the rule (x, y) → (x - 1, y + 6) then reflected across the y- axis. What are the coordinates of A”,B”, and C”?
Answers
The coordinates of A'', B'' and C'' are (-1, 4), (-4, 3) and (-1, 2) respectively.
What is Geometric Transformation?Transformation of geometrical figures or points is the manipulation of a given figure to some other way.
Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.
Given triangle has coordinates,
A(2, -2), B(5, -3) and C(2, -4).
First the triangle is translated by the rule (x, y) → (x - 1, y + 6)
A(2, -2) becomes A'(2 - 1, -2 + 6) = A'(1, 4).
B(5, -3) becomes B'(5 - 1, -3 + 6) = B'(4, 3)
C(2, -4) becomes C'(2 - 1, -4 + 6) = C'(1, 2)
Then the translated triangle is reflected across the Y axis.
When reflected a point (x, y) across the Y axis, y coordinate remains same and x coordinate flips.
A'(1, 4) becomes A''(-1, 4)
B'(4, 3) becomes B''(-4, 3)
C'(1, 2) becomes C''(-1, 2)
Hence the vertices of the triangle after undergoes translation and reflection becomes A''(-1, 4), B''(-4, 3) and C''(-1, 2).

Answer: The use of a divider is to divide things/people.
a red die and a blue die are rolled. you win or lose money depending on the sum of the values of the two dice.if the sum is 5, 6, or 8, you win $5.if the sum is 4, 9, or 10, you win $2.if the sum is any other value (2, 3, 7, 11, or 12), you lose $4.let x be a random variable that corresponds to your net winnings in dollars. what is the expected value of x?
Answers
The expected value of your net winnings, x, is $1.39.
To find the expected value of x (net winnings), first calculate the probability of each outcome and multiply it by the respective winnings. There are 6 sides on each die, so there are 36 possible outcomes (6 sides on red die * 6 sides on blue die).
1. Winning $5: Sum of 5, 6, or 8 has 4+5+5 = 14 successful outcomes. Probability = 14/36.
2. Winning $2: Sum of 4, 9, or 10 has 3+4+3 = 10 successful outcomes. Probability = 10/36.
3. Losing $4: Sum of 2, 3, 7, 11, or 12 has 1+2+6+2+1 = 12 successful outcomes. Probability = 12/36.
Now, multiply each probability by its respective winnings/loss and sum them to find the expected value of x:
E(x) = ($5 * 14/36) + ($2 * 10/36) + (-$4 * 12/36) = $1.39

Given the quadratic equation ax2 + 10x + 2 = 0, determine all values of a that will result in this equation having non-real solutions. Show all work that leads to your answer.
Answers
Answer:
a>12.5.
Step-by-step explanation:
you need to look at the discriminant in the quadratic formula:
\(b^{2} -4ac\)
coming from the quadratic polynomial
\(ax^{2} +bx+c=0\)
In our case, b=10 and c=2, hence, the discriminant is
\(10^2-4*a*2 \\100-8a\)
We will obtain non-real values if the discriminant is less than zero.
Therefore, this condition is written as
\(100-8a<0\)
and we must solve for a. It yields
\(100<8a\\a>\frac{100}{8} \\a>12.5\)
Hence, the answer is a>12.5.
The values of a that will result in this equation having non-real solutions must e greater than 12.5
Given the quadratic equation ax^2 + 10x + 2 = 0
For the equation to have non-real solutions, then b^2 - 4ac < 0
From the given equation;
a = a
b = 10
c = 2
Substitute the given parameters into the formula;
10^2 - 4a(2) < 0
100 - 8a < 0
-8a < -100
8a > 100
a > 12.5
Hence the values of a that will result in this equation having non-real solutions must e greater than 12.5

"
Answers
The Laplace transform solution for the given initial-value problem is y(t) = (1/13)e^(-2t)sin(4t) + (1/13)e^(-2t)cos(4t) + (8/13)t - (8/13) + (s/13)e^(-2t) - (3s/13)e^(4t).
Taking the Laplace transform of the given differential equation and applying the initial conditions, we obtain the transformed equation:
s^2Y(s) + 4sY(s) + 20Y(s) = 8(s-1)/(s^2 + 4) + s/(s^2 + 4) - 3(s+4)/(s^2 + 16) + 7/(s^2 + 16) + 1/13 + 4/13s + 8/13s - 8/13.
Simplifying the transformed equation, we can rewrite it as:
Y(s) = [(8(s-1) + s - 3(s+4) + 7 + (1 + 4s + 8s - 8)/(13s))(s^2 + 4)(s^2 + 16)]/[13(s^2 + 4)(s^2 + 16)].
Expanding the equation and applying partial fraction decomposition, we get:
Y(s) = [(13s^3 + 58s^2 + 28s - 43)(s^2 + 4)(s^2 + 16)]/[13(s^2 + 4)(s^2 + 16)].
Now, we can rewrite Y(s) as:
Y(s) = (13s^3 + 58s^2 + 28s - 43)/(s^2 + 4) - (43s)/(s^2 + 16).
Applying the inverse Laplace transform, we find:
y(t) = (1/13)e^(-2t)sin(4t) + (1/13)e^(-2t)cos(4t) + (8/13)t - (8/13) + (s/13)e^(-2t) - (3s/13)e^(4t).

the agent earns a 6% commission on the first $300,000 of the sales price and 3% of that portion of the sales price that exceeds $300,000. the commission is $21,150. what is the sales price?
Answers
As per the given commission, the sales price of the property is $405,000.
To do this, we need to break down the commission earned by the agent into two parts: the commission earned on the first $300,000 and the commission earned on the remaining amount. The commission earned on the first $300,000 can be calculated as:
Commission on first $300,000 = 6% of $300,000
Commission on first $300,000 = 0.06 x $300,000
Commission on first $300,000 = $18,000
So, the remaining commission earned by the agent on the amount that exceeds $300,000 is:
Total commission - Commission on first $300,000 = $21,150 - $18,000
Total commission - Commission on first $300,000 = $3,150
Now, we know that the commission earned on the remaining amount is 3% of the sales price that exceeds $300,000. Let's assume the sales price of the property is x. Then we can write the following equation:
3% of (x - $300,000) = $3,150
We can simplify this equation as follows:
0.03(x - $300,000) = $3,150
x - $300,000 = $3,150 / 0.03
x - $300,000 = $105,000
x = $300,000 + $105,000
x = $405,000

Did the roman military become too powerful? why or why not
Answers
The question of whether the Roman military became too powerful is subjective and can be interpreted differently based on various perspectives and historical contexts.
The power of the Roman military can be seen as both a strength and a potential concern. On one hand, the military might of ancient Rome played a crucial role in the expansion and maintenance of the empire. The well-disciplined and highly organized legions allowed the Romans to conquer and control vast territories, ensuring stability, protection, and the spread of Roman civilization.
However, the growing power of the Roman military also raised concerns. As the empire expanded, maintaining control over distant regions became a challenge. The need for a large and powerful military to safeguard the empire led to increased military spending, strained resources, and the potential for abuse of power. Moreover, the concentration of military power in the hands of ambitious generals or emperors posed a threat to the stability of the political system.
Ultimately, the question of whether the Roman military became too powerful depends on the perspective taken. From a strategic standpoint, the strength of the military allowed Rome to exert control and protect its interests. However, the potential for military dominance to undermine the balance of power within the empire and lead to political instability should not be disregarded.

Using the Poisson distribution,
a) The probability that the next page you read contain zero typographical error is 0.81. .
b)The probability that the next page you read contain 2 more typographical errors is 0.017..
Given that expected number of typographical errors on a page out of 10 pages of a certain magazine is , λ = 0.20
Let X is a random variable representing the number of typographical error. We use Poisson distribution. The Poisson distribution formula is ,
P(X) = (e⁻λ λˣ)/x!
For part (a) Put X = 0 , we get
P(X=0) = (0.2)⁰e⁻⁰·²/0! = 1/ e⁰·²⁰= 0.8187
b) Find the probability that the next page you read contains 2 more typographical errors.
That is, P(X≥2) = 1- P(X=0) - P(X=1) = 1 - 0.8187 - (0.2)e⁻⁰·² /1!= 1 - 0.9824= 0.0175

"The highest temperature is -5 degrees."
-5 degrees is the lowest temperature, not the highest!
"-5 is warmer than 3 degrees."

An auto dealer has 5 different cars and 6 different trucks. How many ways are there to select three vehicles so that at least one truck is chosen?
Answers
There are 155 ways to select three vehicles so that at least one truck is chosen.
How to determine the number of selecting three vehicles?To solve the problem given above, we first need to calculate the total number of ways of choosing three vehicles without any restrictions. We can do this by using the combination formula.
The number of combinations of n objects taken r at a time is given by:
nCr = n! / r! (n - r)!
where n! is the factorial of n (i.e. the product of all positive integers up to n), r! is the factorial of r, and (n - r)! is the factorial of n - r.
Using this formula, we can calculate the total number of ways of choosing three vehicles as follows:
nCr = 11! / 3! 8! = 11 × 10 × 9 / 3 × 2 × 1 = 165
Now, we need to calculate the number of ways of choosing three vehicles so that no truck is chosen. Since there are 5 cars, we can choose 3 cars in 5C3 = 10 ways.
Therefore, the number of ways of choosing three vehicles so that at least one truck is chosen is given by the difference between the total number of ways of choosing three vehicles and the number of ways of choosing three vehicles so that no truck is chosen.
Thus, the number of ways of choosing three vehicles so that at least one truck is chosen is:

A. 25 m/s
B. 10 km/min
C. 15 mi/h eastward
D. 3 mi/h
Answers
Step-by-step explanation:
Velocity is a measure of the rate at which an object moves through space. It is a vector quantity, meaning that it has both magnitude (size) and direction. The standard unit for velocity is meters per second (m/s).
Of the quantities listed above, the following represent velocities:
A. 25 m/s: This represents a velocity of 25 m/s, because it gives both the speed (magnitude) and direction of the object's movement.
C. 15 mi/h eastward: This represents a velocity of 15 miles per hour (mi/h) in an eastward direction, because it gives both the speed and direction of the object's movement.
D. 3 mi/h: This represents a velocity of 3 mi/h, because it gives both the speed and direction (implied to be eastward or westward) of the object's movement.
B. 10 km/min: This does not represent a velocity, because it gives the distance traveled (10 km) but not the time over which the distance was traveled. Without the time, it is not possible to determine the speed or rate of movement.
