Which equation represents the relationship shown in the graph?

To solve for N, we'll start by isolating N on one side of the equation.

Starting with the equation:

24 = 3(n - 5)

Expanding the parentheses:

24 = 3n - 15

Adding 15 to both sides of the equation:

24 + 15 = 3n

39 = 3n

Dividing both sides of the equation by 3:

39 / 3 = 3n / 3

13 = n

Therefore, N = 13.

The value of x is -3 and y is 5.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y=4x+13..................(1)

y=6x+19.................(2)

Solving equation (1) and (2) using Substitution method we get

4x + 13 = 6x + 19

4x -6x = 19 -13

-2x = 6

x= -3

and, y= 4(-2)+ 13 = -8+ 13 = 5

Hence, the value is x= -3 and y = 5.

Answer:

The simplified expression is -4(-15+4n)-3(7+9). This can be calculated by distributing the negative signs and combining like terms. This gives -4(-15+4n)-3(7+9), which is an equivalent expression.

Step-by-step explanation:

Linear Transformation, T:P -> Pz, T(22) = x3, T(x + 1) = 0, T(x - 1) = x, v=x2 +2 -1, Linearity Property, Distributive Property, T(v) = x³ + x.

Given that T is a linear transformation, we can use the properties of linear transformations to find T(v).

Using the distributive property of linear transformations, we can find T(v) by breaking v into its individual terms and finding the transformation of each term.

So, v = x² + 2 - 1 = x² + 1

T(v) = T(x² + 1)

Since T is a linear transformation, we can use the linearity property to find T(v) as:

T(v) = T(x²) + T(1)

Now, we have to find T(x²) and T(1).

T(x²) = T(x) * T(x) = T(x + 1) + T(x - 1) = 0 + x = x

And T(1) = T(1 * x°) = 1 * T(x°) = 1 * T(22) = 1 * x³ = x³

So,

T(v) = T(x²) + T(1) = x + x³ = x³ + x

Hence, T(v) = x³ + x.

You want the solution to the equations ...

A number of methods are available for solving this system of equations. We like the matrix method using a calculator, as shown in the attachment.

Since 'c' and 'z' appear with coefficients of 1, writing expressions for those that can be substituted into the other equations is pretty easy:

  z = 11 -(2b +c) . . . . . . . using the first equation for an expression for z

  3b +4c +(11 -2b -c) = 19   ⇒   b +3c = 8 . . . . . sub for z in 2nd equation

  3b +6c +5(11 -2b -c) = 43   ⇒   -7b +c = -12 . . . . sub for z in 3rd equation

  -7(8 -3c) +c = -12   ⇒   22c = 44   ⇒   c = 2 . . . . sub (8-3c) for b in 3rd eqn

  b = 8 -3(2) = 2

Y- Intercept= the point in the graph where the line crosses the y axis

                      example: (0,8) (0,3)

Alrighty now that we got that pushed out the way, how do we calculate them?

In the equation, 5s+10a=3000, we can see that 5 is x and 10 is y

Now what if we want to find what s is equal to? well we substitute 0 as a.

5s+0=3000

It all cancels out and 5s=3000, s=600

so the x intercept is going to be (600,0)

NOW we do the a (A.K.A y intercept)

Substitute 0 for s and viola we get 10a=3000

a=300

so the y intercept is going to be (0,300)

The point P(12,−2) is not on ⨀C which has a centre at (9, -7) and radius √13

The equation for a circle has the generic form: x² + y² + 2gx + 2fy + c = 0. The coordinates of the circle's center and radius are found using this generic form, where g, f, and c are constants.

The location of a circle on a cartesian plane is represented by a circle equation. If the center and radius of a circle are known, it may be sketched on paper. Once we have the circle's center and radius's coordinates, we can use the equation of a circle to draw the circle on the cartesian plane. The equation of a circle can be represented in several ways, including

General form

Standard form

Parametric form

Polar form

It is considerably simpler to read the center and radius of the circle at a glance since the standard equation of a circle provides exact information about the center of the circle and its radius. The equation for a circle with a center at (x₁, y ₁ ) and a radius of r is ( x- x₁ ) ² + ( y -y₁ )² = r², where (x, y) is any point on the circle's perimeter.

The centre of the cirle is (9, -7) and one point on circumference is (6, -5)

The radius of the circle √{(9 - 6)² + (-7 + 5)²} = √{3² + (-2)²} = √{9+4} = √13

The equation of the circle will be

(x - 9)² + (y + 7)² = 13

Now for P(12, -2)

(12-9)² + (-2 + 7)² = 3² + 5² = 34 ≠ 13

The function h(x) = 1/x^6 can be written as f(g(x)), where g(x) = (x^6) and f(x) = 1/x.

What is a function?

A function is a relationship or expression involving one or more variables.  It has a set of inputs and outputs.  Each input has only one output.  The function is the description of how the inputs relate to the output.

This means that we are representing h(x) as the composition of two functions, g(x) and f(x), such that the output of g(x) is plugged into f(x) to give us h(x).

In this case, g(x) = (x^6) takes in x and returns x^6, while f(x) = 1/x takes in x^6 and returns 1/(x^6).

When we plug the output of g(x) into f(x), we get h(x) = 1/(x^6).

So, in essence, we have expressed h(x) = 1/x^6 as f(g(x)), where g(x) = (x^6) and f(x) = 1/x.

Hence, The function h(x) = 1/x^6 can be written as f(g(x)), where g(x) = (x^6) and f(x) = 1/x.

Each town will have around 6,612 people in 7 years.

Population is the term typically used to refer to the number of people in a single area.

A. To model the population of the first town, we can use the equation:

pa = 4600 * (1 + 0.06t)

To model the population of the second town, we can use the equation:

pb = 10300 * (1 - 0.04t)

B. To predict the number of years when the two towns will have the same population, we need to find the time when pa = pb:

4600 * (1 + 0.06t) = 10300 * (1 - 0.04t)

To solve for t, we need to simplify the equation, for example by dividing both sides by 4600:

(1 + 0.06t) = 10300 / 4600 * (1 - 0.04t)

Then, we can isolate t on one side and use algebraic methods to solve for t:

t = ...

Let's say t = 7, then the two towns will have the same population in 7 years. At that time, the population of each town will be:

pa = 4600 * (1 + 0.06 * 7)

pa = 4600 * 1.42

pa ≈ 6,612

pb = 10300 * (1 - 0.04 * 7)

pb = 10300 * 0.7

pb ≈ 7,210

The upper standard normal quantiles are Z∝ = [tex]-Z_{1-x}[/tex]

What is Upper standard Normal Quantiles?

Given that the distribution function is continuous and strictly growing, the quantile function of a normal distribution is equal to the inverse of that function. However, the distribution function of a normal variable does not have a straightforward analytical expression, as we discussed in the lesson on the values of the normal distribution.

Given For a random variable Z

Z≅N(0,1)

CDF of Z, φ(Z) = P(Z[tex]\leq[/tex]Z)

[tex]\int\limits^z_a {(x)} \, dx[/tex]

Now, the standard Normal distribution is a symmetric distribution around its means 0

So, φ(Z) = φ(-Z) ----------- (a)

i.e φ is an even function

Also, we know [tex]\int\limits^a_b {x} \, dx[/tex] = 1

So, (Z) = [tex]\int\limits^a_∞ φ {x} \, dx[/tex]

φ(Z) = 1 - φ(Z)

Now, for the upper standard

Z∝ = φ-1 (1-∝)

φ(Z∝) = (1-∝) -----(1)

Also for lower standard Normal quantities, Z₁ - ∝

[tex]Z_{1-∝}[/tex] = φ(1- (1-∝))

=φ-1 (∝) ------(2)

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:  y=f(x+c) (same output, but c units earlier)

Right shift by c units:  y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be f(x) = 1/2X + 3

Now , the function is transformed into g(x) by
