if X is a rational number and Y is the opposite of X, why do X and Y have the same absolute value
In mathematics, the absolute value of a number represents its distance from zero on the number line. If X is a rational number and Y is the opposite of X, their absolute values are the same because they are the same distance from zero, regardless of direction.
Explanation:In the realm of mathematics, rational numbers have a property called absolute value. The absolute value of a number is its distance from zero on the number line, regardless of direction. So, if X is a rational number, Y being its opposite means it is the same distance from zero, but in the other direction.
For example, if X = 3 (a rational number), then Y = -3 (the opposite of X). Despite X and Y being opposites, their absolute values are the same: |3| = |-3| = 3, as both are 3 units away from zero.
Hence, no matter what values X and Y may have, if Y is the opposite of X (either positive or negative), their absolute values will always be equal because they are the same distance from zero.

f is increasing over the interval 0 < x < 2.
f(2) = 3.
f is decreasing over the interval 2 < x < 5.
In Mathematics and Geometry, a function f(x) is considered as an even function if the following condition holds for all x-values (both positive x-values and negative x-values) in the domain of function f(x):
f(x) = f(-x) ⇒ symmetrical with y-axis.

The first step is to figure out what angle DEB is equal to. Check out the attached image. I've marked this as angle y and it is shown in purple.
Note how the purple angle y and the orange 160 degree angle form a straight angle (180 degrees). So the two angles add to 180. Let's solve for y
(orange angle) + (purple angle) = straight angle
(angle CEB) + (angle DEB) = angle CED
y+160 = 180
y+160-160 = 180-160 ... subtract 160 from both sides
y = 20
----------------------------------
Now we can use this to figure out angle x. The three angles x, 115, and 20, combine to 180 degrees as they all glue together to form a straight angle. Let's solve for x:
x+115+y = 180
x+115+20 = 180 ...replace y with 20
x+135 = 180 ......... combine like terms
x+135-135 = 180-135 ...... subtract 135 from both sides
x = 45
Therefore, the final answer is 45
the area of each square is 16 square units find the perimeter of a figure
The perimeter of the rectangular pattern, formed by arranging 16 squares with an area of 16 square units in a 4x4 layout, is 16 units.
To determine the perimeter of a rectangular pattern formed by arranging 16 squares, each with an area of 16 square units, in a 4x4 layout, we can follow these steps.
First, we know the area of each square is 16 square units, which means the side length of each square is the square root of 16, which is 4 units.
Now, when these squares are arranged in a 4x4 pattern, you have 4 squares along the length and 4 squares along the width. The length and width, in terms of these squares, are both 4 squares.
The perimeter of a rectangular shape is calculated using the formula: Perimeter = 2 × (Length + Width).
Plugging in the values:
Perimeter = 2 × (4 + 4) = 2 × 8 = 16 units.
So, the perimeter of the resulting figure is 16 units. This means, when you trace the outline of this 4x4 arrangement of squares, the total distance around the shape is 16 units. Each side contributes 4 units, and there are four sides, giving us a total perimeter of 16 units. This calculation follows the basic principles of perimeter for rectangular shapes and applies them to the given arrangement.

You have invested in three different stocks: Engineering Aces, Upton Clothiers, and Thompson Musical Instruments. Because you have diversified your stocks so well, the way they change is independent. The probabilities of the stocks changing in value by more than 10% in a given week are listed below.
P(E) = 19%
P(U) = 11%
P(T) = 6%
What is the probability that all three will change by more than 10% in the same week?
Answer:
answer is 0.001254.
Step-by-step explanation:
Given that you invested in 3 stocks of Engineering Aces, Upton Clothiers, and Thompson Musical Instruments.
Also given that each stock value is independent of the other.
Let E be the event changing in value by more than 10% in a given week for Engineering Aces,
U be the event changing in value by more than 10% in a given week for Upton Clothiers, and T be the event changing in value by more than 10% in a given week for Thompson Musical Instruments.
Given that P(E) = = 19%
P(U) = 11%
P(T) = 6%
probability that all three will change by more than 10% in the same week
= P(EUT)
= P(E) P(U) P(T) since three events are independent.
=0.19(0.11)0.06
= 0.001254
Final answer:
The probability that all three stocks, Engineering Aces, Upton Clothiers, and Thompson Musical Instruments, will change by more than 10% in the same week is calculated by multiplying their individual probabilities together, resulting in a probability of 0.1254%.
Explanation:
The question asks for the probability that all three stocks will change by more than 10% in the same week, given their individual probabilities.
To find this probability, since the changes in stocks are independent of each other, we multiply the probabilities of each event occurring together. The formula for the joint probability of independent events is P(E and U and T) = P(E) × P(U) × P(T).
Using the given probabilities:
P(E) = 19% or 0.19P(U) = 11% or 0.11P(T) = 6% or 0.06We calculate:
P(E and U and T) = 0.19 × 0.11 × 0.06
Which equals:
P(E and U and T) = 0.001254 or 0.1254%
Therefore, the probability that all three stocks will change by more than 10% in the same week is 0.1254%.

6y-5x=5 and x=2y+7 using substition in linear functions
6y-5x=5 x=2y+7
x=2y+7 x=2(-10)+7
6y-5(2y+7)=5 x= -20+7
6y-10y-35=5 x= -13
6y-10y=5+35
-4y=40
y= -40/4
y=-10
Final answer:
To solve the given system using substitution, express x from the second equation and substitute into the first, then solve for y. After finding y, substitute it back into the second equation to find x, resulting in x = -13 and y = -10.
Explanation:
Solving Linear Equations Using Substitution Method
To solve the system of linear equations 6y - 5x = 5 and x = 2y + 7 using the substitution method, we first take the second equation, which gives us an expression for x, and substitute it into the first equation.
Step 1: Write the second equation x = 2y + 7.
Step 2: Substitute x in the first equation: 6y - 5(2y + 7) = 5.
Step 3: Expand and simplify: 6y - 10y - 35 = 5 ⇒ -4y = 40 ⇒ y = -10.
Step 4: Now that we have y, we substitute it back into the second equation to find x: x = 2(-10) + 7 ⇒ x = -20 + 7 ⇒ x = -13.
Therefore, the solution to the system of equations is x = -13 and y = -10.
David plants a tree that is 3 feet tall. at the end of the 4 years it has grown to be 6 feet tall, and then stops growing. after 7 years, david cuts down the tree to put in a pool. what is the domain, in years, of the function that represents the height of the tree?
The domain of the function is (0, 7) years.
The function that represents the height of the tree is defined over the period during which the tree's height changes. Given that,
The tree starts growing at 0 years (the time when it is first planted). It grows for 4 years, reaching a height of 6 feet by the end of that period. After 4 years, the tree stops growing and remains at 6 feet for the remaining 3 years. After 7 years total (4 years of growth + 3 years of constant height), the tree is cut down.
The domain of the function that represents the height of the tree is the time interval from when the tree is planted until it is cut down.
what is the solution to {2x +3y=11 and 3x+3y=18
Answer:
The ordered pair that satisfies the equation is (7, -1)
Step-by-step explanation:
In order to find this, we can solve by subtracting. Start by stacking the two equations on top of one another and subtracting like terms.
3x + 3y = 18
(-) 2x + 3y = 11
--------------------
x = 7
Now that we have the value for x, we can plug in to either equation to find y.
2x + 3y = 11
2(7) + 3y = 11
14 + 3y = 11
3y = -3
y = -1
Final answer:
By applying the method of subtraction to eliminate one variable, we find that the solution to the system of equations 2x + 3y = 11 and 3x + 3y = 18 is x = 7 and y = -3.
Explanation:
Solving a System of Linear Equations
The two linear equations given are:
2x + 3y = 113x + 3y = 18To find the solution, we can follow a method similar to the one described for solving simultaneous linear equations. We can subtract the first equation from the second to eliminate the variable y:
3x + 3y = 18-(2x + 3y = 11)This gives us x = 7. Now we can substitute x back into either equation to get the value of y:
2(7) + 3y = 11
By solving this, we get y = -3.
The solution to the system of equations is x = 7 and y = -3.
