Hi there! The answer is 3, 6, 7, and 9.
1,2,4,5,8, and 10 cannot be put as denominators because if so, there would be:
1. no decimals
2. termination after one or two decimal places.
Cheers!

Answer:
Option C: X=1
Step-by-step explanation:
2(X + 8) - 4x = 10x + 4
2X + 16- 4X= 10X + 4
-2X +16 =10X + 4
16 - 4 = 10X+2X
12 =12X
X=1
Answer:
y=-4x+5
Step-by-step explanation:
y+3=-4(x-2)
y+3=-4x+8
-3. -3
y=-4x+5
Answer:
3/4
Step-by-step explanation:
sin = opposite/hypotenuse
one side is 3, hypotenuse side is 5.
using the pythagorean theorem, we know that the third side is 4.
tan = opposite/adjacent
tanθ = 3/4
Answer:
Step-by-step explanation:
Usually, this wording means the decrease is proportional to the current price, characteristic of an exponential function.
__
The decay factor is 1-(decay rate), so is 1-0.15 = 0.85. After 3 years, the value has been multiplied by this factor 3 times:
$50×0.85³ ≈ $30.71 . . . . cost in 3 years
_____
<em>Comment on percent per year</em>
Less often, the indicated decrease is intended to be <em>that percentage of the original price</em>. The result is that the price decreases by a constant amount each year, a linear decrease. This condition most often arises in conjunction with figuring depreciation in value for tax or accounting purposes.
The upshot is that you always need to be careful to understand what the base of a percentage is intended to be.
