What does h(40) =1400 mean in terms of the problem ?

Step-by-step explanation:

Because in chart we have the values of both variables, dependent and independent. So, according to that information, 40 hours of training relates with a result of $1400 monthly pay.

So, the notation:

Means that 40 belongs to the independent variable and 1400, the result, it's the dependent one, because the money depends on how many hours of training.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
