Please help me understand this problem.

__________________________________________________________

Step-by-step explanation:

We are given:

3 + 10 - 2 - 10

Concepts used:

Evaluating Mixed fractions and Adding like terms

Simplifying the Mixed Fractions:

to simplify these mixed fractions, we will multiply the whole number part with the fraction's denominator and add that to the numerator.

The number formed will be given the same denominator as of the fraction part in the number

After simplifying these mixed fraction, we get:

Adding and Subtracting the like terms:

to simplify our calculations, we will pair the numbers with the same denominator

Simplifying the terms in the brackets

Taking the LCM and simplifying

Since the denominators are equal, the numerators can now be subtracted

Therefore, simplifying the given series of number gives us 31x/45

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.
