Answer:
Option A.Exponential decay, 55% decrease
we have
This is a exponential function of the form
where a is the initial value
b is the base
b=(1+r)
r is the rate of change
In this problem
a=54
b=0.45
so
0.45=1+r
r=0.45-1
r=-0.55
Convert to percentage
r=-55% ------> is negative because is a exponential decay
Answer:
83
Step-by-step explanation:
Angle 7 & angle 8 are supplementary angles, meaning they add up to 180º.
Angle 8 & angle 12 are corresponding angles, so they are equal.
If we solve for the measure of angle 8, it will be the same answer as angle 12.
Therefore, angle 7 & angle 12 add up to 180º.
80 + (x+17) = 180
Solve:
(80-80) + (x+17) = 180-80
X+17 = 100
X + (17-17) = 100-17
X = 83
<h2>d) X= - 16/9</h2>
Step-by-step explanation:
2x - 4 - 6(x + 1) = 5x + 6
2x - 4 - 6x - 6 = 5x + 6
2x - 6x - 5x = 4 + 6 + 6
-9x =16
x= -16/9
