Answer:

f^-1(x) = 1/5 x

Step-by-step explanation:

y = 5x

Exchange x and y to find the inverse

x = 5y

Solve for y

1/5x = y

The inverse is 1/5x

Answer:

\Large \boxed{f^{-1}(x)=\frac{x}{5} }

Step-by-step explanation:

f(x) = 5x

Replace f(x) with y.

y = 5x

Switch variables.

x = 5y

Divide both sides by 5.

\frac{x}{5} =y

The average rate of change of <em>g(x)</em> over the interval [2, 8] is given by

(<em>g</em> (8) - <em>g</em> (2)) / (8 - 2)

In other words, it's the slope of the line through the points (2, <em>g</em> (2)) and (8, <em>g</em> (8)).

Use the definition of the function to evaluate it at the points in the numerator:

• 8 ≥ 4, so using the second piece, <em>g</em> (8) = -0.5(8) + 8 = 4

• 2 < 4, so <em>g</em> (2) = 5(2) + 1 = 11

Then the average rate of change is

(<em>g</em> (8) - <em>g</em> (2)) / (8 - 2) = (4 - 11) / 6 = -7/6

leo knows that each time a digit moves one place to the left in a whole number the value of the digit is 10 times as much. descr
Serga [27]

Answer:

Leo is true for any numbers (including decimal numbers)

Step-by-step explanation:

* Lets explain how to solve the problem

- In number 256

# 6 is the unit digit (one digit)

# 5 is the ten digit (10 digit)

# 2 is the hundred digit (100 digit)

- If we change the number to 2563

# 6 digit is moved 1 place to the left now its place changed from unit

  digit to ten digit (from 1 to 10) that means 6 in the second number

  is 10 times the 6 in the first number

# 5 digit is moved 1 place to the left now its place changed from ten

  digit to hundred digit (from 10 to 100) that means 5 in the second

  number is 10 times the 5 in the first number

# 2 digit is moved 1 place to the left now its place changed from  

  hundred digit to thousand digit (from 100 to 1000) that means 2

  in the second number is 10 times the 2 in the first number

- In number 2.345

# 2 is the unit digit (one digit)

# 3 is the tenth digit (1/10 digit)

# 4 is the hundredth digit (1/100 digit)

# 5 is the thousandth digit (1/1000 digit)

- If we change the number to 23.45

# 3 digit is moved 1 place to the left now its place changed from tenth

  digit to unit digit (from 1/10 to 1) that means 3 in the second number

  is 10 times the 3 in the first number

# 4 digit is moved 1 place to the left now its place changed from  

  hundredth digit to tenth digit (from 1/100 to 1/10) that means 4 in the

  second number is 10 times the 5 in the first number

# 5 digit is moved 1 place to the left now its place changed from  

  thousandth digit to hundredth digit (from 1/1000 to 1/100) that means

  5 in the second number is 10 times the 5 in the first number

∴ Leo is true for any numbers (including decimal numbers)

The vertex angle of an isosceles triangle is 20° less than the sum of the base angles. Which system of equations can be used to
WINSTONCH [101]

The answer to the above question can be explained as under -

We know that, the sum of angles of triangle is 180°.

So, vertex angle plus base angles are equal are equal to 180°.

Let the vertex angle be represented by "v" and base angles be represented by "b".

Thus,  v + b + b = 180°

So,  v + 2b = 180°

Next, the question says, the vertex angle is 20° less than the sum of base angles.

Thus, 2b - 20° = v

<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>
