Answer:
False
Step-by-step explanation:
The disjunction evaluates to ...
false or false
In order for an "or" statement to evaluate to True, at least one of the elements needs to be true. That is not the case here, so the disjunction is false.
Answer:
2x + 5y = -15 OR 2x + 5y + 15 = 0 Not sure they want it equal to zero
Step-by-step explanation:
y + 7 = -2/5(x - 10)
y + 7 = -2/5 x + 4
2/5x + y =-3
5(2/5 x + y = - 3)
2x + 5y = - 15
OR
2x + 5y + 15 = 0
Answer: x = 2.4 or 12/5, y = -1.2
Step-by-step explanation:
-2x + y = -6
=> y = 2x - 6
-x + 3y = -6
=> -x + 3(2x - 6) = -6
=> -x + 6x - 18 = -6
=> 5x = 12
=> x = 12/5 or 2.4
-x + 3y = -6
=> - (2.4) + 3y = -6
=> 3y = -6 + 2.4
=> 3y = -3.6
=> y = - 1.2
Answer: A = -2/5
Step-by-step explanation:
- 6/5 - 2/5 = - 8/5 aka - 1 3/5
-1 3/5 ÷ 4 = - 2/5
