Linear or non linear?

Answer:
Linear
Step-by-step explanation:
This is linear because using the data you have provided we can work out that the equation is y= -5x+27
y= mx+ c (c is the gradient)
This equation shows that the line is straight (also shown in the picture) and therefore must make it a linear graph.
For the graph to be non linear, the graph would be curved but this would mean the equation would have to be a quadratic - which it isn't.
Hope this helps!

Answer:
The minimum acceptable weight of the flour bag is 39.5 kg,
and its maximum acceptable weight is 40.5 kg
Step-by-step explanation:
Notice that the selling weight of the bag to be sold (x) needs to differ from 40 kg at most 0.5 kg. Therefore, we can write the following inequality:
The inequality can be solve once we remove the absolute value symbol, and solve for the unknown "x". Recall that in order to solve it, we need to consider the two possible cases:
a) that the expression within the absolute value symbol is larger than or equal to zero, and b) that the expression is less than zero.
a) If then its absolute value is equal to itself (x-40), and when we remove the absolute value symbols, we get:
which means that the weigh "x" of the flour bag should be smaller or equal than 40.5 kg
b) If , then the absolute value of this is its opposite : -x+40, and the inequality becomes:
which means that the weight of the flour bag must be larger than or equal to 39.5 kg
So, the minimum acceptable weight of the flour bag is 39.5 kg, and the maximum acceptable weight is 40.5 kg
