Since it’s 4 peace’s there’s a 1 out of 4 chance for each of them meaning it’s 25% for each or likely

If x is divided by 2 and then 4 is subtracted, then the function is f left parenthesis x right parenthesis equals x divided by 2

Anni [7]

The inverse is y = x/2 - 4

Steps involved are -

replace f(x) with y: y = 2(x + 4)
Then switch y and x: x = 2(y + 4)
Finally make y the subject:
x = 2(y + 4)
x/2 = y + 4 (divide by 2)
x/2 - 4 = y (subtract 4)
So, the inverse is y = x/2 - 4

<h3>What is the formula for inverse function?</h3>

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
The inverse of f exists if and only if f is bijective.

f-1(y) = y/2 = x, is the inverse of f(x).

1.06g - 3 = 0.71 I need this answer

Arte-miy333 [17]

Simplifying 1.06g + -3 = 0.71 Reorder the terms: -3 + 1.06g = 0.71 Solving -3 + 1.06g = 0.71 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 1.06g = 0.71 + 3 Combine like terms: -3 + 3 = 0 0 + 1.06g = 0.71 + 3 1.06g = 0.71 + 3 Combine like terms: 0.71 + 3 = 3.71 1.06g = 3.71 Divide each side by '1.06'. g = 3.5 Simplifying g = 3.5

Write an equal ratio for the fraction 5/7

jeyben [28]

Answer:

To find an equal ratio, you can divide or multiply by the same number on the top and bottom of the fraction. For example...

5 x 2 = 10

7 x 2 14

So, by multiplying 5 and 7 by 2, 10/14 is another fraction that is equal to 5/7. Here's some more possible answers if you need them...

5 x 3 = 15

7 x 3 21

5 x 4 = 20

7 x 4 28

Solve each system by substitution. y=3x+4 y=4x+7

Y_Kistochka [10]

We need to solve the following system by substituition:

$\begin{cases}y=3x+4 \\ y=4x+7\end{cases}$

To solve by substituition means that we need to isolate one variable in one of the equations and replace one expression with the other. This is done below:
