Answer:
The value of b is -5
Step-by-step explanation:
A linear equation is represented as:
.
The equation of the line is: 
First, we calculate the slope (m) of 
Make y the subject

Divide by 18

In 
slope
So, the slope of
is:

Since, the line is perpendicular to 
The slope of the line is:

So, we have:


The line passes through (4,-2).
So, the equation is:

This gives:



Hence, the linear equation is:

10% of 40 =
10% × 40 =
.10 × 40 = 4.00
Tax is $4
Amount Paid is 40 + 4 = $44
Y≤x/3-1 AND y≤x/3-3
So for BOTH inequalities to be true:
y≤x/3-3
