3/5 mile in 1/20 hours =3 minutes . so in 1 minute he skates 1/5 of a mile . in 60 minutes he skates 12 miles . speed is 12mph
Answer:
( f + g ) (x) = 
g(x) - f(x) = 
Step-by-step explanation:
- f(x) = 4 x - 4 and g(x) =

( f + g ) (x) = f(x) + g(x)
= 
= 
2. g(x) =
and f(x) = 2 x + 5
g(x) - f(x) = 
= 
= 
Answer:
The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I
Step-by-step explanation:
To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.
8x + 6y = 48
4x - 6y = -12
-------------------
12x = 36
x = 3
Next, find the y value by plugging in the x value to either equation and solving.
2x - 3y = -6
2(3) - 3y = -6
6 - 3y = -6
-3y = -12
y = 4
The Commutative law. It states a * b = b * a.
So, cba is the same as abc.
You are going to treat this as a triangle so one side is 13 units long and the other is 22. And using the pythagorean theorem a²+b²=c².
13²+22²=c²
169+484=c²
653=c²
√653=√c²
25.55386...=c
Or, rounded to the nearest hundredth, 25.55
