(_ , _) means (X , Y)
(25 , ) means
X = 25 then you need find the value of Y from the equation .
so the first answer is (25,-3)
..............
( , -8) means
Y = -8 then you need to find the value of X from the equation .
so the second answer is ( 0 , -8 )

Answer:
The problem does not work.
Step-by-step explanation:
The plane with speed of 31 mph will cover 640 miles in hours.
Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.
So, it will burn in 20.64 hours gallons.
Now, the helicopter with speed of 45 mph will cover 640 miles in hours.
Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.
So, it will burn in 14.22 hours gallons.
But both of them starts with only 80 gallons of fuel.
Therefore, the problem does not work. (Answer)
Answer:
Step-by-step explanation:
Subtract 3 from both sides:
Subtract 10x from both sides:
Divide both sides by -3:
Answer:
The solution set is (5,6).
Step-by-step explanation:
Given equations are:
-6x + 6y= 6 Eqn 1
-6x + 3y=-12 Eqn 2
Subtracting Eqn 2 from Eqn 1
(-6x+6y)-(-6x+3y)= 6-(-12)
-6x+6y+6x-3y=6+12
3y = 18
Dividing both sides by 3
Putting y=6 in Eqn 1
-6x+6(6)=6
-6x+36=6
-6x=6-36
-6x=-30
Hence,
The solution set is (5,6).
