Therefore, the transformation of the double integral can be expressed as follows: ∫∫g(x', y') (x' + 1)(y' - 1) dx' dy' = ∫∫g(x', y') (x' + 1)(y' - 1) |J| dA'

the alteration of variables A mathematical trick known as a formula is used to switch the variables in an integral from one set of variables to another. The integral is frequently simplified or made easier to solve by doing this. Given a function f(x) and two sets of variables x and y, the integral of f(x) with respect to x may be represented as the integral of a transformed function g(y) with respect to y, where g(y) is connected to f(x) by a functional connection between x and y. For instance, the integral of f(x) with respect to x can be expressed as the integral of f(sqrt(y)) with respect to y if x and y are connected by the equation y = x2.

How to solve?

x' = x - 1

y' = y + 1

∫∫g(x, y) xy dA = ∫∫g(x', y') (x' + 1)(y' - 1) dx' dy'

∫∫f(x, y) dA = ∫∫f(x', y') |J| dA'

|J| = | ∂x'/∂x ∂x'/∂y |

| ∂y'/∂x ∂y'/∂y |

|J| = | 1 0 |

| 1 1 |

Therefore, the transformed double integral can be expressed as follows:

∫∫g(x', y') (x' + 1)(y' - 1) dx' dy' = ∫∫g(x', y') (x' + 1)(y' - 1) |J| dA'

m = slope

Use two points on the graph to find  m

    m = ( x1-x2)/(y1-y2)  = ( 1- -1) / ( -4 - -2) =  2 / -2 = -1

A regression line is an approximation of the line that describes the true, but unknown, linear connection between two variables. The regression line equation is used to predict (or estimate) the value of the response variable from a given value of the explanatory variable.

In statistical modeling, regression analysis is a collection of statistical techniques for estimating the associations between a dependent variable and one or more independent variables.

By substituting these values in equation 1 we get,

If a math test is worth 100 points and has 30 problems and  each problem is worth either 3 or 4 points, then there are 10 4 point problems

Total number of questions = 30

Number of 3 point questions = x

Number of 4 point questions = y

The first equation will be

x + y = 30

x = 30-y

Total score of the test = 100 points

Then the second equation will be

3x + 4y = 100

Here we have to use the substitution method, substitute the value of x in the equation

3(30-y) + 4y = 100

90 - 3y +4y = 100

y = 100 - 90

Step-by-step explanation:

Answer:

x = - 3 and y = - 8

Step-by-step explanation:

the equation of a vertical line parallel to the y- axis is

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (- 3, - 8 ) with x- coordinate - 3 , then

x = - 3 ← equation of vertical line

the equation of a horizontal line parallel to the x- axis is

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 3, - 8 ) with y- coordinate - 8 , then

y = - 8 ← equation of horizontal line

The parabola has a vertex at (-3, -2), has a p-value of 3 and it opens up.

Mathematically, the vertex form of a parabola is represented by this mathematical expression:

y = a(x - h)² + k

Where:

h and k represents the vertex of the equation.

In Mathematics, the focus for either a right or left parabola is modeled by this mathematical expression (h + p, k) while its directrix is modeled by this mathematical expression x = h - p;

h + p = 0   ⇒ h = -p

h - p = -6

Solving the set of linear equations simultaneously, we have:

-p - p = -6

-2p = -6

p = 6/2

p = 3

For the value of h, we have:

h = -3.

Additionally, the vertex form of this parabola is given by:

y = a(x - h)² + k

y = a(x - 3)² - 2

y + 1 = (-7/6)(x - 3)

y + 1 = (-7/6)x + 7/2

The measure of the angle is 39°.

Complementary angles are angles whose sum is equivalent to 90°. On the other hand, supplementary angles are angles whose sum is equivalent to 180°.

Let x be the measure of the angle.

90° - x = complement angle of x

180° - x = supplement angle of x

If the measure of its supplement is 39 more than twice the measure of its complement, then

180° - x = 39 + 2(90° - x)

Simplify and solve for x.

180° - x = 39 + 2(90° - x)

180° - x = 39 + 180° - 2x

We have to find the value of 40% of 75.

Percentage;

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The sign "%" is used to denote it.

Now,

Lets find;

40% of 75

40/100 × 75 = 40/4 × 3 = 10 × 3 = 30

That is,

40% of 75 is 30.

Now,

2/5 of 75

2/5 × 75 = 2 × 15 = 30
