Tara's science project was graded based on creativity, accuracy, and effort. If she received a 9.4 for each of the three citeria, what was her total score

Tara's total score = 28.2

Step-by-step explanation:

We are told that her science project was graded based on creativity, accuracy, and effort.

Now, she received a score of 9.4 for each of these criteria.

Thus;

Score for creativity = 9.4

Score for accuracy = 9.4

Score for effort = 9.4

So,

total score = 9.4 + 9.4 + 9.4 = 28.2

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.
