The inverse function returns the original value for which the output of a function was given.

[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2 be the inverse the function y = (1 - 2x)² + 5.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value. The inverse of f is then g(y) = (y - 5)/2 = x.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Let the equation be y = (1 - 2x)² + 5

simplifying the above equation, we get

√(x - 5) y = (1 - 2x)² + 5

x = (1 - 2y)² + 5

The function of x be x = (1 - 2y)² + 5

x - 5 = (1 - 2x)²

± √(x - 5) = (1 - 2y)

± √(x - 5) - 1 = 2y

Divide both sides of the equation by 2, we get

[± √(x - 5) - 1]/2 = 2y/2

[± √(x - 5) -1] /2 = y

[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2

Therefore, the inverse of the function be [tex]y^{-1}[/tex] = -1 ± √(x - 5) /2.

We get that when the expression 5 ∛ 9 y² . ∛ 24 y is simplified using multiplication, we get the result as 30 y.

We are given the expression:

5 ∛ 9 y² . ∛ 24 y

We need to multiply to simplify the expression.

First, we know that:

9 = 3 × 3

24 = 2 × 2 × 2 × 3

So,

∛ 24 = 2 ∛ 3

So, we get the expression as:

5 ∛ 9 y² . 2 ∛ 3 y

Multiply the terms, we get that:

10 ∛ 27 y³

= 30 y

Therefore, we get that when the expression 5 ∛ 9 y² . ∛ 24 y is simplified using multiplication, we get the result as 30 y.

The expanded form of 3(2x -3y -2) is given by the equation 6x -9y -6

The equation given is a linear equation in two variables and to simplify the equation 3(2x -3y -2), we need to use algebraic properties

The algebraic property used here is distributive property which says that a (b+ c) = ab + ac.

So, let us expand the equation using the algebraic property mentioned above

As a= 3, b=2x and c=3y+2

  3(2x -3y -2)

  3 (2x) -3(3y+2)

Using the property again with a=3, b=3y and c=2

     3 (2x) -3(3y+2)

     6x -3(3y) -3(2)

     6x - 9y -6

Hence, the expanded form of 3(2x -3y -2) is given by the equation 6x -9y -6

f(4) means what is the value of f(x) when x = 4

substitute x = 4 into f(x)

f(4) = 2(4) - 5 = 8 - 5= 3

-----------------------------------

2

substitute x = - 1 into g(x)

g(- 1) = 3(- 1)² + 5 = 3(1) + 5 = 3 + 5 = 8

--------------------------------------

3

substitute x = 4 into h(x)

h(4) = 3(4) + 2 = 12 + 2 = 14

--------------------------------------

(f + g)(- 2)

= f(- 2) + g(- 2)

= 2(- 2) - 5 + 3(- 2)² + 5

= - 4 - 5 + 3(4) + 5

= - 9 + 12 + 5

= - 9 + 17

= 8

-----------------------------------------

(f + h)(2)

= f(2) + h(2)

= 2(2) - 5 + 3(2) + 2

= 4 - 5 + 6 + 2

= - 1 + 8

= 7

-------------------------------------------------

(f - g)(- 3)

= f(- 3) - g(- 3)

= 2(- 3) - 5 - (3(- 3)² + 5)

Two expressions with an equal sign is called as Equation.

Let the two numbers be a and b.

Given equation is a-b=12 .....(1) and

The first number is 5 less than twice the second number i.e a=2b-5

Substitute a in (1)

2b-5-b=12

b-5=12

b=17

b=17 is the second number.

Now we have to find first number so

The equation of the line that passes through (2, -6) and is perpendicular to the given line is y = -x -4

From the question, we are to determine the equation of a line that passes through (2, -6) and it perpendicular to y = x + 4

If two lines are perpendicular, the product of their slope is -1.

That is,

m₁m₂ = -1

First,

We will determine the slope of the line that the equation was given

y = x + 4

Comparing with the slope-intercept form of the equation of a straight line

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison

m = 1

The slope of the line that the equation was given is 1

Thus,

The slope of the line that is perpendicular to this line is -1

From the given information,

The line passes through the point (2, -6)

Using the point-slope form of the equation of a line

y - y₁ = m(x - x₁)

Then,

y - -6 = -1(x - 2)

y + 6 = -x + 2

y = -x + 2 - 6

y= -x -4

Hence, the equation of the described line is y = -x -4

Based on the expression the number of grid squares in a character of size 7 is 55

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression for the number of grid squares in a character of size s is given as

6 + s^2

Rewrite the expression as a function

So, we have

f(s) = 6 + s^2

To find the number of grid squares in a character of size 7, we set s to 7

i.e. s = 7

So, we have

f(7) = 6 + 7^2

Evaluate the exponent

So, we have

f(7) = 6 + 49

Evaluate the sum

So, we have

f(7) = 55

Hence, the number of grid squares in a character of size 7 is 55

Another technique to clarify exponents in mathematics is through logarithms. A base number's logarithm equals another number.

For instance, log10 100 = 2 if 102 = 100. A logarithm is defined as an influence by which variety must be raised to receive another value. this is often the foremost convenient thanks to represent large numbers. Logarithms have several important properties that prove that logarithmic multiplication and division is written because the logarithm of addition and subtraction. The log is named the logarithm of base e. The logarithm is represented by ln or loge. where 'e' represents Euler's constant,  approximately capable 2.71828. as an example, the log of 76 is written as ln 76. The log defines what percentage times 'e' must be multiplied to induce the required output.

We need to evaluate log₄₉7

Using Property

logₙ (a) = 1 / logₐ (n)

log₄₉7 = 1/ log₇ 49

Using the properties of log again logₐ (mⁿ) = n logₐ m

49 = 7²log₇ 49

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given statement is,

The product of a number m and 1.7 is 6.63

Thus, converting it into numerical form we get,

1.7m = 6.63

Dividing both the side by 1.7 we get,

1.7m/1.7 = 6.63/1.7

Solving we get,

m = 3.9
