Answer:
Without solving, the solution is greater than 21. The can be proven because a fraction of x is equal to 21, therefore x cannot be less than 21.
Step-by-step explanation:
Answer:
Step-by-step explanation:

Hence, on base 10, the next whole number is 4995 and if we convert back to base 9, we will have

Therefore, the number on base 9 will be 6750

The required equation of the line is y = -1/2x
<h3>Equation of a line</h3>
The standard equation of a line is expressed as y = mx + b
- where:
- m is the slope
- b is the y intercept
Given the coordinate points (0,0) and (4, -2)
Slope = -2/4 = -1/2
The intercept is 0 since the line pass through the origin
Hence the required equation of the line is y = -1/2x
