The given equations are
- 7x - 4y = 4
3x + 9y = - 9
We would solve both equations simultaneously. We would apply the method of elimination. To eliminate y, we would multiply the first equation by 9 and the second equation by 4. The new equations would be
- 63x - 36y = 36
12x + 36y = - 36
Adding both equations, we have
- 63x + 12x - 36y + 36y = 36 - 36
- 51x = 0
Dividing both sides of the equation by - 51, we have
- 51x/- 51 = 0/- 51
x = 0
Substituting x = 0 into - 7x - 4y = 4, we have
- 7 * 0 - 4y = 4
0 - 4y = 4
- 4y = 4
Dividing both sides of the equation by - 4, we have
- 4y/- 4 = 4/- 4
y = - 1
The correct option is (0, - 1)

Let T be the three dimensional solid bounded from above by the half cylinder described by the equation z = √(9 - y) and from below the cy plane for 0 ≤ x ≤ 2 and -3 ≤ y ≤ 3. Let S be the closed surface that completely surrounds T. Let F➜ = (x,y,y+z). Use the Divergence Theorem to calculate ∫∫S F • n dS
Using the Divergence Theorem, we get the flux of F across the closed surface S is π/2 (27√2 - 27).
To apply the Divergence Theorem, we will first compute the divergence of F as follows -
div(F) = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z
= 1 + 1 + 1
= 3
Now we will calculate the flux of F across the closed surface S that completely surrounds T. By the Divergence Theorem, this is equal to the triple integral of the divergence of F over the region T and is given by -
∫∫S F•n dS = ∭T div(F) dV
We can describe the region T using cylindrical coordinates:
0 ≤ r ≤ 2
-π/2 ≤ θ ≤ π/2
0 ≤ z ≤ √(9 - r sin θ)
The bounds on r and θ come from the fact that the half cylinder is contained within the plane x = 2, and the plane y = ±3. The bounds on z come from the equation of the half cylinder.
Now we can write the triple integral as follows -
∭T div(F) dV = ∫0^2 ∫-π/2^π/2 ∫0^√(9 - r sin θ) 3 r dz dθ dr
Evaluating this integral, we get,
∭T div(F) dV = π/2 (27√2 - 27)
Therefore, the flux of F across the closed surface S is π/2 (27√2 - 27).

The table shows the number of yearbooks sold and the price needed to cover the costs of printing. What function models the data?
The data modelling function is Price required to recoup printing expenses is equal to 0.1 * (numbers of yearbooks sold) + 45.
What is an annual?A yearbook is a collection of images and text that is issued by an organisation once a year to remember and highlight the happenings at a particular school during the previous academic year. Yearbooks were used in elementary, middle, high, and college and university settings throughout the 20th century.
Using the information in the table,
\(n = 5\)
Σ\(x = 1175\)
Σ\(y = 145\)
Σ\((xy) = 41000\)
Σ\((x^2) = 287500\)
When these values are inserted into the formula,
\(m = (541000 - 1175145) / (5*287500 - 1175^2)\)
\(= -0.1\)
Therefore, the slope of the linear function is \(-0.1\).
\(b = y - mx\)
where we can use any of the data points. Let's use\((250, 20)\)
\(b = 20 - (-0.1*250)\)
\(= 45\)
Therefore, the y-intercept of the linear function is \(45\).
\(y = -0.1x + 45\)
Therefore,
Price needed to cover the costs of printing \(= -0.1*\)(number of yearbooks sold) \(+ 45\).

Step 2 The admission price increased by 50%. Complete the bar diagram that represents 150% of the price 5 years ago. price 5 years ago = $3 So, the current admission price is current price = + or --- increase 150%
The bar diagram representing 150% of the price 5 years ago would be a bar with a height of $4.50.
What is the percentage?
Percentage is a way to express a number as a fraction of 100. It is often used to describe the relationship between two quantities, or to express a rate or change in a quantity over time. The symbol for percent is "%".
For example, if a pizza is marked up by 20%, it means the price has increased by 20/100 or 1/5 of the original price. If a student scores 80% on a test, it means they got 80 out of 100 questions correct. If a stock's value increases by 10%, it means the value has gone up by 10/100 or 1/10 of the original value.
The current admission price is $3 + $3 * 50% = $3 + $1.50 = $4.50.
150% of the price 5 years ago is $3 * 150% = $3 * 1.5 = $4.50.
So, the bar diagram representing 150% of the price 5 years ago would be a bar with a height of $4.50.

(q1) Find the length of the curve described by the function
The value of the Integral at the lower limit from the value of the integral at the upper limit to get the length of the curve.
The length of the curve described by the function f(x) = 1 + 3x^2 + 2x^3 is to be found. The formula used to find the length of a curve is:
L = ∫(sqrt(1 + [f'(x)]^2))dx where f'(x) is the derivative of f(x)We have to first find f'(x):f(x) = 1 + 3x^2 + 2x^3f'(x) = 6x + 6x^2
The integral becomes:L = ∫(sqrt(1 + [6x + 6x^2]^2))dx = ∫(sqrt(1 + 36x^2 + 72x^3 + 36x^4))dx The integral appears to be difficult to evaluate by hand.
Therefore, we use software like Mathematica or Wolfram Alpha to solve the problem. Integrating the expression using Wolfram Alpha gives:
L = 1/54(9sqrt(10)arcsinh(3xsqrt(2/5)) + 2sqrt(5)(2x^2 + 3x)sqrt(9x^2 + 4))The limits of integration are not given. Therefore, the definite integral be solved.
We can, however, find a general solution. We use the above formula and substitute the limits of integration.
Then, we subtract the value of the integral at the lower limit from the value of the integral at the upper limit to get the length of the curve.

Find the side length of a cube with a volume of 141 f3 If necessary, round your answer to the nearest tenth.
The side length of the cube is 5.6 feet (rounded to the nearest tenth).
We can calculate the side length of a cube with a volume of 141 cubic feet using the formula for cube volume , which is \(V = s^3\), where V is the volume and s is the side length.
We can calculate s by taking the cube root of both sides of the equation:
\(s = (V)^{(1/3)\)
Substituting V = 141, we get:
\(s = (141)^{(1/3)\)
By using a calculator to evaluate this expression, we may determine:
s ≈ 5.6
As a result, the cube's side length is roughly 5.6 feet (rounded to the closest tenth). This indicates that if we increase the side length by three, it will become longer. (\(s^3\)), we will get the volume of the cube, which is 141 cubic feet.

Answer:
a. x^4 - 12x^3 + 2x^2 - 2x + 4
Degree: 4
b. x^4 - 2x^2 - 2x - 4
Degree: 4
Step-by-step explanation:
For part a, all you are doing is adding the polynomials together. They already set up the boxes in standard form, so all you need to do is add each like term as I wrote out in the answer. The degree is then going to be the first exponent that you see once the polynomial is in standard form, which is 4.
For part b, you are now subtracting the polynomials. Again, it is set up for you in standard form. There is no x^3 terms because they cancel out, but you basically subtract each like term from another, and remember to distribute the subtraction sign (it acts as a -1) across the parenthesis. The degree is the first exponent you see, and that is 4.
X=Y+Y xy So, x=X-Y/Yy True False
The statement X = Y + Yxy is True.
The equation given is:
X = Y + Yxy
To find x = (X- Y) / Yy we have to substitute the value of x in X = Y + Yxy as
X = Y + Yxy
X = Y + Yy (X-Y) / Yy
To solve for x, we can rearrange the equation as:
X = Y + X - Y

- There are 130 people in a sport centre,
76 people use the gym,
60 people use the swimming pool,
32 people use the track,
23 people use the gym and the pool.
8 people use the pool and the track
20 people use the gym and the track,
6 people use all three facilities,
A person is selected at random
What is the probability that the person uses exactly one of the facilities?
Answer:
0.6462 = 64.62% probability that the person uses exactly one of the facilities
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
20 people use the gym and the track and 6 people use all three facilities
So 20-6 = 14 use exactly the gym and the track and 6 use all three.
8 people use the pool and the track
So 8 - 6 = 2 use exactly the pool and the track.
23 people use the gym and the pool.
So 23 - 6 = 17 use exactly the gym and the pool.
32 people use the track
So 32 - (6 + 14 + 2) = 10 use only the track.
60 people use the swimming pool
So 60 - (6 + 2 + 17) = 35 use only the pool.
76 people use the gym
So 76 - (6 + 14 + 17) = 39 use only the gym
What is the probability that the person uses exactly one of the facilities?
Out of 130, 39 + 35 + 10 = 84 use exactly one of the facilities.
84/130 = 0.6462
0.6462 = 64.62% probability that the person uses exactly one of the facilities

4x3 = -5x - 21 solve for x
To solve for x in the equation 4x3 = -5x - 21, we can follow these steps:
1. Move all the terms containing x to one side of the equation, and move the constant term to the other side. We can do this by adding 5x to both sides and then adding 21 to both sides:
4x3 + 5x = -21
2. Factor out x from the left-hand side of the equation:
x(4x2 + 5) = -21
3. Divide both sides by (4x2 + 5):
x = -21 / (4x2 + 5)
So the solution for x is x = -21 / (4x2 + 5). Note that this is a rational function, which means that the value of x depends on the value of the variable x. This equation has no real solutions because the denominator is always positive, and the numerator is negative.

What is an equation?An equation is an algebraic statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 6x + 11 = 14, for instance, the two expressions 6x + 11 and 14 are separated by the symbol "equal (=)"
x= 2y -30 ............. (1)
5x-2y=10 ............. (2)
substitute x= 2y-30 into the 2nd equation
or, 5(2y-30)-2y = 10
or, 10y-150-2y=10
or, 10y -150-2y= 10
or, 8y-150=10
After adding 150 on both sides we get:
or, 8y = 160
so, y = 20
substitute y=20 into x = 2y-30
so, x = 40-30
so x = 10 & y = 20
thus, 10 blocks did Jack and Jill each walk.

For a line with a slope a and a known point (h, k), the point-slope form is:
y = a*(x - h) + k
How to write an equation in point slope form?A general linear equation can be written in slope-intercept form as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that a line passes through a point (h, k), then the point-slope form of that line is:
y = a*(x - h) + k
Notice that particularly, the y-intercept can be written as (0, b), then the slope-intercept form is also a point-slope:
