1 answer:
Eddi Din [679]2 years ago
3 0

Answer:

x  = - 1,  y = 4

Step-by-step explanation:

A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.

B.

  x + 2y = 7

<u>+ 3x - 2y  = -11</u>

 4x         = - 4

  x         = - 1

x + 2y = 7

-1 + 2y = 7

     2y = 8

       y = 4

A fraction is less than 1. Choose a counterexample that will prove this conjecture false​
Vesnalui [34]

Answer:

1st option

Step-by-step explanation:

Here we are trying to prove that not all fractions are less than 1. So we have to choose an example in which the fraction is more than 1.

1) \frac{8}{7}  = 1 \frac{1}{7}

This fraction is greater than 1 hence it can prove that the conjecture is false.

2) ½ is lesser than 1 and will not prove that the conjecture is false.
