Answer:
f⁻¹(x) =
Explanation:
To get the inverse of a function, we have to follow these steps:
1- replace f(x) with y
2- swap the x and y variables
3- solve for y
4- replace y with f⁻¹(x)
Applying this to the given as follows:
f(x) =
Step 1: replace f(x) with y:
y =
Step 2: swap the x and y variables:
x =
Step 3: solve for y:
7x = 4y - 3
4y = 7x - 3
y =
Step 4: replace y with f⁻¹(x):
f⁻¹(x) =
Hope this helps :)

Step-by-step explanation:
This is a linear equation in slope intercept form which is
where m is the slope and b is the y intercept.
The equation
Has a slope of -1/3 so this means that the slope will be decreasing. A negative linear equation increases as we go left. and decreases as we go right. The y intercept is 2. So this means the graph must pass through (0,2) and when x=0, y must be 2.
In other words, look for a line that the y values increase as we go left and decrease we go right. Also look for a point (0,2) and make sure the graph pass through it.
Answer:
$1.10
Step-by-step explanation:
We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.
First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.
Now, we will divide $5.50 by 5 to find cost of each avocado.
Therefore, the cost of each avocado is $1.10.
