Expand each logarithm.
log₃ 7(2 x-3)²

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

The inverse the function y = 2x + 1 is [tex]y^{-1[/tex] = x + 1/ 2.

Every logarithmic function has an exponential inverse, and vice versa.

An exponential function is a mathematical function with the formula f(x) = ax, where "x" is a variable and "a" is a constant that is called the function's base and must be greater than zero.

The transcendental number e, which is approximately equal to 2.71828, is the most commonly used exponential function base.

Let the equation be y = 2x + 1

y = 2x + 1

simplifying the equation, we get

⇒ 2x = y+1

⇒ x = y+1/ 2

Therefore, the inverse is [tex]y^{-1[/tex] = x+1/ 2

Let the composition function be

[y ₀ [tex]y^{-1[/tex]] (x) = y (x+1/2)

simplifying the above equation

[y ₀ [tex]y^{-1[/tex]] (x) = 2 (x+1/2)-1

[y ₀ [tex]y^{-1[/tex]] (x) = x

The inverse of y is the image of y in the line y = x.

Answer:

-18 + 30 s - 72 t + 12 u

Step-by-step explanation:

Expand the following:

-6 (3 - 5 s + 12 t - 2 u)

-6 (3 - 5 s + 12 t - 2 u) = -6×3 - 6 (-5 s) - 6×12 t - 6 (-2 u):

-6×3 - 6 (-5) s - 6×12 t - 6 (-2) u

-6×3 = -18:

-18 - 6 (-5) s - 6×12 t - 6 (-2) u

-6 (-5) = 30:

-18 + 30 s - 6×12 t - 6 (-2) u

-6×12 = -72:

-18 + 30 s + -72 t - 6 (-2) u

-6 (-2) = 12:

Answer:  -18 + 30 s - 72 t + 12 u

Answer:

y=2880x+26500

Step-by-step explanation:

Basically, this question wants you to write an equation where you can figure out how much money Tony has at any year.

1. They already told us how much the raise was: $2880

2. He started off with $26,500, so we know we have to add that at the beginning. That is our y-intercept.

3. A function is written as y=mx+b. Y is what you are solving for. M is the constant change (x doesn't mean anything, it just tells us which number is m). B is the y-intercept, which is 26,500 in this case. Its what you are starting with. If he had no money, there would be nothing to start with. There would be no y-intercept.

4. Because he gets the same raise every year of 2880, that is constant. It does not change, but it increases constantly.

5. So, y=2880x+26500 is your answer.

The missing terms in the given factorized expression are:

3x²y + 12xy² + 9xy = 3xy ( x + 4y + 3 )

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.

We have,

_ x²y + _ y² + 9 _ = 3x _ ( _ + 4y + _ )

We need to fill the boxes and make sure that both sides are equal.

We will remove the bracket on the right side.

i.e 3x _ _ + 12xy_ + 3x_ _

Now,

_ x²y + _ y² + 9 _ = 3x _ _ + 12xy_ + 3x_ _

We will make,

_ x²y  and 3x _ _ equal.

_ y²  and 12xy_ equal.

9 _  and + 3x_ _ equal.

So,

(3)x²y = 3x (x)(y)

9 (xy) = 3x(y)(3)

Thus the missing terms in the given factorized expression are:

x = 9 is not an extraneous solution of the equation.

√x=√(x-8) + 2

Squaring both the sides of the equation, we get

(√x)² = (√(x-8)+2)²

x = (✓(x - 8))² + 2² + 2(✓(x - 8))(2)

x = x - 8 + 4 + 2(✓(x - 8))(2)

Subtracting x on both the sides of the equation, we get

- 4 + 2(✓(x - 8))(2) = 0

Adding 4 on both the sides of the equation, we get

4(✓(x - 8)) = 4

Dividing both sides of the equation by 4, we get

(✓(x - 8)) = 1

Squaring again on both the sides of the equation

x - 8 = 1

x = 9

Check for extraneous solution by putting the value of x = 9 in the original equation, we get

✓9 = ✓(9 - 8) + 2

✓9 = ✓1 + 2

3 = 1 + 2

3 = 3

⇒ LHS = RHS

∴ x = 9 is not an extraneous solution of the equation.

The linear equation of the graph is y = x - 5

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The graph represents the given parameter

On the graph, we have the following points

(x, y) = (1, -4) and (5, 0)

Calculate the slope (m) using

m = (y2 - y1)/(x2 - x1)

So, we have

m = (0 + 4)/(5 - 1)

Evaluate

m = 1

The equation is then calculated as

y = m(x - x1) + y1

So, we have

y = 1 * (x - 5) + 0

Evaluate

y = x - 5

Hence, the linear equation of the graph is y = x - 5

The exponential function for to represent the balance of the account will be y = 14 ( 1.16) ˣ

We have that:

The saving account has initially = $ 14

After 1 year, the balance became = $ 16.24

After 2 years, the balance became = $ 18.84
Difference in the initial amount and amount after 1 year = $ 16.24 - $ 14 = $ 2.24

Difference in the amount after 1 year and amount after 2 years = $ 18.84 - $ 16.24 = $ 2.60.

An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.

by using the operation of multiplication, we get that 21 days is equal to 3 weeks, 504 hours, 30240 minutes and 1,814,400 seconds.

We are given the total number of days as 21.

Now, we know that:

In 1 week, we have 7 days.

So, in 3 weeks = 7 × 3 = 21 days.

Also, 1 day has = 24 hours.

So, by using multiplication, we get that:

21 days = 24 × 21 hours

= 504 hours

Also,

1 hour = 60 minutes

504 hours will be calculated again by using multiplication.

504 hours = 504 × 60 = 30240 minutes

The partial derivatives for this problem are given as follows:

To find the partial derivatives of a function, we apply the same rules that we apply for complete derivatives, just considering the variables for which we are not deriving the function as constants.

For this problem, the function is given as follows:

x² + 4y² + 7z² = 1.

The function for z is given by:

7z² = 1 - x² - 4y²

[tex]z = \sqrt{\frac{1 - x^2 - 4y^2}{7}}[/tex]

As a function of x, the derivative will be given by:

[tex]\frac{\partial z}{\partial x} = -\frac{x}{\sqrt{\frac{1 - x^2 - 4y^2}{7}}}[/tex]

Because the derivative of the inside term as a function of x is of -2x, then we apply the derivative of the root and simplify -2 with 2.

For the derivative as a function of y, we follow the same procedure, with the lone difference being the the inside derivative is of -8y, then:

[tex]\frac{\partial z}{\partial y} = -\frac{4y}{\sqrt{\frac{1 - x^2 - 4y^2}{7}}}[/tex]
