3+5.2x=1-2.8x
1. 3+5.2x+2.8x=1
2. 5.2x+2.8x=1-3
5.2x+2.8x=1-3
1. 8x=1-3
2. 8x=-2
8x=-2
1. =-(1/4)
Alternative form:
2. x=-0.25
Answer:
c
because it is
Step-by-step explanation:
The expression is:

Why?
From the statement we know that the spaceship travels 3 times faster each minute that it traveled during the minute before, it can be expressed using an exponential function, its base will be the starting speed (during the first minute).
The expression will be:

Have a nice day!
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
y is the value of the home
x is the number of years
a is the initial value
r is the rate of change
we have

substitute


Answer:
Increasing
−5<x<−1
−1<x<1
Decreasing
