Answer:
To break even, Liza must answer 2 questions correctly to give her 6 points, because she now has negative 6 points a the result would be a score of 0
Step-by-step explanation
multiply negative 2 by the 3 incorrect questions, and you get negative 6.
divide 6 by 3 to get 2 to find the number of questions she needs to make correct to break even.
5x - y³ = 135x - y³ = 13
The answer can be obtained by simply putting the ordered pair into the equations. First (2 , -9)
5(2) - (9)³ = 135(5) - (-9)³ = 13
10 + 729 = 675 + 729 = 13
739 = 1404 = 13
This is not true. Therefore this is not a solution
Second (3,-6)
5(3) - (-6)³ = 135(5) - (-6)³ = 13
231 = 891 = 13
This is also not true
Therefore, neither ordered pair is a solution.
