Question:

Tim has to write two papers worth 50 points each. to pass, he has to get at least 45% of the total points. however, scoring less than 30% of the points on either paper, even if his total for both papers is above 45%, will result in him failing. which graph represents the region in which tim fails? (assume that he scores x points on paper a and y points on paper b.)

Thank you for posting your question here at I hope the answer will help you. Feel free to ask more questions.

Based on the above situation the graph that represents the region in which Tim fails is the graph A. 

Solution:

As, Given

Points scored in Paper A= x

Points scored in paper B= y

The Conditions in terms of equations which are applied , for passing of Tim is

Score should be above , 30% of 50=[tex]\frac{30}{100}\times 50[/tex]= 15 and 45% of 100=[tex]\frac{45}{100} \times 100= 45[/tex]

1. x  > 15

2. y  > 15

3. x +y ≥ 45

The set of equations represent , if Tim fails

a. x< 15

b. y < 15

c. x +y ≤45

Option (C)
