Answer:
- p ⇒ - q
Step-by-step explanation:
p : Drive over 65 miles
q : You get a speeding ticket.
So then we get the negations.
- p : You do not drive over 65 miles
- q : You don't get a speeding ticket.
So, we need to connect the sentences. For that we use ⇒.
⇒ : then.
So, the sentence, If you do not drive over 65 miles per hour, then you will not get a speeding ticket
Can be written as : -p ⇒ -q
There are 109 pairs. Hoped this helps:)!
(6--3)/(1--5)=9/6=3/2=1.5
-3x + y - 2z = 10 |* -1
3x - y +2z = -10
5x -2y -2z = 12
--------------------------- I add these equations term by term
8x - 3y = 2
-3x + y - 2z =10 ⇒ -3x + y - 2z =10
x -y +z = 23 | *2 2x - 2y + 2z = 46
----------------------------- I add these eq.
-x -y = 56
8x - 3y = 2
-x -y = 56
this is the system after i reduce it ( it has only two variables x and y)
