Define the two numbers
------------------------------------------------------------
Let one number be x and the other be y
------------------------------------------------------------
Form equations and solve
------------------------------------------------------------
x + y = -14 --------------- (1)
y - x = 12 ------------------(2)
------------------------------------------------------------
(1) + (2)
------------------------------------------------------------
2y = -2
y = -1
------------------------------------------------------------
Substitute y = -1 into (2)
------------------------------------------------------------
y - x = 12
-1 - x = 12
x = -1 -12
x = -13
------------------------------------------------------------
Answer: x = -13, y = -1

Answer:
I think is f(n) = 3 + 3(n - 1)
Step-by-step explanation:
Because it goes up 3 in price and 1 in gallons of gas
Answer:
y = 3/x
Step-by-step explanation:
It would be 6 miles per hour.
mph is a unit for speed. And the formula for speed is s=distance /time
So the distance is 2 miles
And the time is 20 minutes
*for this question you need to convert the minutes to hours to get the right units
20mins =0.3 hours (approx) [20/60 to get it in hours]
2 miles/0.3 hours ≈ 6 mph
Answer:
first box is parallel
Second box perpendicular
Third box neither
Fourth box neither
Fifth box perpendicular
Sixth box is parallel
Why? Slopes of parallel lines are the same. Slopes of perpendicular lines are opposite reciprocals. (Example slope=1/2 a perpendicular line would be -2/1). Neither is just a when it’s not either parallel or perpendicular.
Hope this helps
