Answer:
34.4x
Step-by-step explanation:
Using exponential function concepts, it is found that it represents a decay of 0.9%.
<h3>What is an exponential function?</h3>
A decaying exponential function is <em>modeled </em>by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function is:

Hence:


Thus, it represents a decay of 0.9%.

Answer:
x = 9
Step-by-step explanation:
A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is
=
=
( cross- multiply )
8(3x - 20) = 56
24x - 160 = 56 ( add 160 to both sides )
24x = 216 ( divide both sides by 24 )
x = 9
2x + 2x+2 = -134
4x + 2 = -134
4x = -136 |: 4
x = -34
2x = 2 * (-34) = -68
2x + 2 = -68 + 2 = -66
This numbers are -66 and -68.
