3/20x = 9.......with x being the total cost of the food
x = 9 / (3/20)
x = 9 * 20/3
x = 180/3
x = 60 <===
Answer:
1.) 1
2.) 3600
3.) 242
Step-by-step explanation:
1- 523 / 523 = 1
2- 12 x 300 = 3600
3- 144 + 98 = 242
Answer:
The inverse of logarithmic function
f⁻¹(x)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given f(x) = log₂ˣ ( 2 is a radical)
<em>Let x₁ and x₂ be the ∈ domain f</em>
⇒f(x₁) = f(x₂)
⇒ ![log_{2} x_{1} = log_{2} x_{2}](https://tex.z-dn.net/?f=log_%7B2%7D%20x_%7B1%7D%20%3D%20%20log_%7B2%7D%20x_%7B2%7D)
⇒ x ₁ = x₂
<em>Therefore f(x) is one-one function</em>
Let y = f(x) = log₂ˣ
⇒ y = log₂ˣ
⇒
<em>f(x) is a one-one function and onto</em>
⇒
⇒ f⁻¹(x)
<em>The inverse of logarithmic function </em>
f⁻¹(x)
Answer:
Equation
Step-by-step explanation:
It has a equal sign so that makes it a equation.
(-5x - 9) - (-6x -1)
- 5x - 9 + 6x + 1
x - 8
