Step-by-step explanation:
Since the inequality is already written in y=mx+b, you can easily graph the line. +3 is the y intercept, so one point would be (0,3). -2 resembles the slope, so diagonally to the left, you would go up 2 and across 1. Also, since the sign is "<" you would graph with a dotted line. Then to know which side to shade, I always use the coordinate (0,0). I plug in 0 for both x and y to see if (0,0) satisfies the inequality. In this case it does, so you would shade on the side where (0,0) is located.
The difference between the two mass is 151950g
Data;
- Mass a = 29.48kg
- Mass b = 181,430g
To calculate the difference between the mass, we must do so in the same unit. i.e both mass a and mass b must be in the same unit.
<h3>Conversion of Mass from Kg to g</h3>Let's convert mass a from kg to g
Using this, we can find how many grammes are in 29.48kg
Now we can find the difference between mass b and mass a
The difference between the two mass is 151950g
