Answer:
f(1/3) = 1
Step-by-step explanation:
Plug 1/3 in for n
f(1/3) = 3(1/3)
Now simplify
f(1/3) = 1 { 3(1/3) = (3/1)(1/3) = 3/3 = 1 }
Answer: x = 28
Step-by-step explanation:
x + 20=3x-36
20=2x-36
56=2x
56/2=28
So 28= x
In this case you have:

An hour has sixty minutes.

<span>You must multiply by this equality.

<span>You must multiply by 60 and you can convert miles per minute to miles per hour.</span>
Answer:
x = 2 and y = 5
Step-by-step explanation:
2x = 2
x = 2
-4 + y = 1
y = 5
Answer:
(11, -13)
Step-by-step explanation:
A is at (3, -5) and B is at (13, -15)
A point that is ⅘ of the way from A to B also divides the differences of the x-and y-coordinates in the same ratio.
For the x-coordinate,
x₂ - x₁ = 13 - 3 = 10
⅘ × 10 = 8
3 + 8 = 11
The x-coordinate of the point is x = 11.
For the y-coordinate,
y₂ - y₁ = -15 - (-5) = -15 + 5 = -10
⅘ × (-10) = -8
-5 + (-8) = -13
The y-coordinate of the point is at y = -13.
The coordinates of the point are then (11, -13).
The diagram below shows the point ⅘ of the way from A to B.
