Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
----> 
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate
Answer:-3
Step-by-step explanation:
Answer:
x=−2/5
y−2
Step-by-step explanation:
5x+2y=−10
Step 1: Add -2y to both sides.
5x+2y+−2y=−10+−2y
5x=−2y−10
Step 2: Divide both sides by 5.
5x
5
=
−2y−10
5
x=
−2
5
y−2
Answer:
36 cubic feet
Step-by-step explanation:
