Step-by-step explanation:
Part A: Linear Equation.
- One of the points is (0,15). This means 0,15 is the y intercept so b=15.
We can find the slope

So our equation is

Part B: Exponential Equation
We know that

B to the zero power is 1 so

This means a =15. Now let find b.


So the equation is

Answer: 0.12
Explanation:
3/25 = 0.12
Answer:
(-1, 7)
Step-by-step explanation:
2 unites left would movie from 1 to -1.
1 unit down would move from 8 to 7.
Answer:
9.275 inches or 9 11/40
Step-by-step explanation:
current depth = beginning depth - inches swam up + inches swam down
8 3/4 - 2 3/5 + 3 1/8
= 9 11/40
22 would be the answer. You reverse the equation so you multiply 3 and add 7 5x3 = 15 15+7= 22
