X+y=6
Simultaneously equations
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=15;x+y=6
Rewrite equations:
x+y=6;2x+3y=15
Step: Solvex+y=6for x:
x+y=6
x+y+−y=6+−y(Add -y to both sides)
x=−y+6
Step: Substitute−y+6forxin2x+3y=15:
2x+3y=15
2(−y+6)+3y=15
y+12=15(Simplify both sides of the equation)
y+12+−12=15+−12(Add -12 to both sides)
y=3
Step: Substitute3foryinx=−y+6:
x=−y+6
x=−3+6
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=3
Answer:
x = 3, y = 3
Step-by-step explanation:
Given the 2 equations
2x + 3y = 15 → (1)
x + y = 6 → (2)
Multiplying 2) by - 2 and adding to (1) will eliminate x
- 2x - 2y = - 6 → (3)
Add (1) and (3) term by term to eliminate x
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(3) = 15
2x + 9 = 15 ( subtract 9 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Henry wraps a gift box in the shape of a square pyramid. The figure below shows a net for the gift box.
The amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².
What is the Surface Area of a Square Pyramid?Surface area of a square pyramid = area of the square base + area of the 4 triangular faces = s² + 4(1/2bh).
We are asked to find the amount of wrapping paper that would be needed to wrap the gift box, which is the surface area of the gift box that has a square pyramid shape.
Given the following dimensions of the gift box:
s = 5.2 in.
b = 5.2 in.
h = 6.7 in.
Plug in the values into s² + 4(1/2bh):
Surface area of a square pyramid = 5.2² + 4(1/2 × 5.2 × 6.7).
Surface area of a square pyramid = 96.72 in.²
Therefore, the amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

Complete the square to transform the expression x2 6x 5 into the form a(x − h)2 k. (x 6)2 4 (x 6)2 − 4 (x 3)2 − 4 (x 3)2 4
An equation is formed of two equal expressions. The equation x²+6x+5 into the form a(x − h)²+k is written as (x+3)²-4.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The transformation of the equation from x²+6x+5 into the form a(x − h)²+k can be done in the following steps as shown below,
1. Taking +5 on the right-hand side of the equation,
\(x^2+6x+5 = 0\\\\x^2+6x = -5\)
2. Now if we add +9 on both sides of the equation, we will get,
\(x^2+6x = -5\\\\x^2+6x+9 = -5+9\)
3. Now we look at the left side of the equation as the square of the binomial expression (x+3).
\(x^2+6x+9 = -5+9\\\\(x+3)^2 =4\)
4. Taking +4 from the right side of the equation to the left side of the equation,
\((x+3)^2 =4\\\\(x+3)^2 -4=0\)
Thus, the equation is in the form of a(x − h)²+k, where the value of a is 1, h is -3 and the value of k is -4.
Hence, the equation x²+6x+5 into the form a(x − h)²+k is written as (x+3)²-4.

Answer: 243.6
Step-by-step explanation:
For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.
Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.

This question is from my final exam review:
Let n be a randomly selected integer from 1 to 15. Find P(n < 10 | n is prime). Round to the nearest hundredth and put your answer as a DECIMAL. So, if your answer is 37%, then put .37 in the answer box.
The probability P(n < 10 | n is prime) is 4/6, which simplifies to 2/3 or approximately 0.67 (rounded to the nearest hundredth).
To find the probability P(n < 10 | n is prime), we need to determine the number of prime integers less than 10 and divide it by the total number of integers from 1 to 15 that are prime.
The prime numbers less than 10 are 2, 3, 5, and 7. So, there are 4 prime numbers less than 10.
The total number of integers from 1 to 15 that are prime is 6 (2, 3, 5, 7, 11, and 13).
As a result, the chance P(n 10 | n is prime) is 4/6, which can be expressed as 2/3 or, rounded to the nearest hundredth, as around 0.67.
Thus, 0.67 is the answer.

Find the largest open interval where the function is changing as requested decreasing; f(x)=x^3-4x
The largest open interval where f(x) is decreasing is (-2√(1/3), 2√(1/3)). In interval notation, this can be written as (-2√(1/3), 2√(1/3)).
To determine where the function f(x) = x^3 - 4x is decreasing, we need to find the intervals where the derivative is negative. Let's calculate the derivative of f(x) first:
f'(x) = 3x² - 4
To find where f'(x) < 0, let's solve the inequality:
3x² - 4 < 0
Adding 4 to both sides gives:
3x² < 4
Dividing both sides by 3 gives:
x² < 4/3
Taking the square root of both sides (and considering both the positive and negative square root) gives:
x < √(4/3) and x > -√(4/3)
Simplifying further, we have:
x < 2√(1/3) and x > -2√(1/3)

We need to investigate the behavior of the derivative of the feature. If the spinoff is negative inside a c program language period, then the quality is lowering over that c language.
Let's begin by finding the derivative of the function f(x) = x^3 - 4x:
f'(x) = 3x^2 - 4
we set f'(x) < zero:
3x^2 - four < zero.
Now, permit's remedy this inequality:
3x^2 < 4,
x^2 < four/three,
x^2 - 4/three < 0.
To find the critical points, we set x^2 - 4/three = zero:
x^2 = 4/three,
x = ±√(4/three),
x = ±2/√3.
We need to test the durations among the essential factors and beyond.
For x < -2/√3, allow's select x = -1. Plugging this cost into f'(x):
'(-1) = three(-1)^2 - four = -1.
Since f'(-1) < zero, the characteristic is decreasing for x < -2/√3.
For -2/√three < x < 2/√three, permits select x = zero. Plugging this price into f'(x):
f'(0) = 3(0)^2 - four = -four.
Since f'(0) < zero, the characteristic is lowering for -2/√three < x < 2/√3.
For x > 2/√three, permits choose x = 1. Plugging this cost into f'(x):
f'(1) = three(1)^2 - four = -1.
Since f'(1) < 0, the function is decreasing for x > 2/√3.
Therefore, the largest open c language in which the characteristic f(x) = x^3 - 4x is lowering is (-∞, 2/√three).

The probability that one player gets all aces is 0.0467
Finding the probability that one player gets all aces.From the question, we have the following parameters that can be used in our computation:
Cards, n = 52
Players, r = 4
The 52 cards can be shared to the the 4 players in C(n + r - 1, r - 1) ways
So, we have
C(52 + 4 - 1, 4 - 1) = C(55, 3)
When evaluated, we have
C(52 + 4 - 1, 4 - 1) = 26235
Next:
The remaining 48 cards can be shared to the other 3 players in C(n + r - 1, r - 1) ways
C(48 + 3 - 1, 3 - 1) = C(50, 2)
C(48 + 3 - 1, 3 - 1) = 1225

assuming there is a linear relationship between the variables, what is the predicted grade for a student with 11 absences?
The predicted grade for a student with 11 absences can be calculated using the equation y = mx + b, where y = predicted grade, m = the slope of the linear regression line, x = the number of absences, and b = the y-intercept. The predicted grade for a student with 11 absences is 79.5.
The linear regression equation is used to predict the value of a dependent variable (y) based on the value of an independent variable (x). The equation takes the form y = mx + b, where m is the slope of the regression line and b is the y-intercept. To calculate the predicted grade for a student with 11 absences, we first need to determine the value of m and b. This can be done by plotting the data points on a graph and calculating the slope and y-intercept of the regression line. Once we have the values of m and b, we can plug them into the linear regression equation. For example, if the slope is -0.5 and the y-intercept is 90, then the predicted grade for a student with 11 absences would be y = (-0.5 * 11) + 90 = 79.5. In this way, the linear regression equation can be used to predict the grade of a student based on the number of absences.

Draw the snapshot graph D (x,t=0s) of this wave at t=0s.
The snapshot graph of the wave at t=0s is a graph of the displacement of the wave along the x-axis at time t=0s.
It is a graph of the wave's initial position, which is usually a sinusoidal graph with a maximum value at the center and decreasing values as x increases. This is because the wave is traveling from left to right and its amplitude decreases as it moves further from its source. To explain in more detail, a sinusoidal wave is a wave that oscillates up and down in a regular pattern.
The snapshot graph at t=0s will show the wave at its highest point, which is the amplitude of the wave. As the wave moves along the x-axis, its amplitude will decrease as it moves further from its source. The graph will also show the wave's wavelength, which is the distance between two successive crests or troughs.
