The scenario represents a linear function. The rate is at a constant increase therefore it is linear.
Linear because it’s a constant rate
Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function
Exponential since it increases by a multiplicative rate. It’s not constant
I believe the answer is the second one I am in the same class.
There is no solution. Because the absolute value function finds the distance between the number and 0. And length is never negative.
So, |-x| = -10 has no solution.
3f+3=t
s=2f
21=f+s+t
21=f+(2f)+(3f+3)
21=6f+3
18=6f
3=first
6=second
12=third
