Answer:
Move to the left of the horizontal number line to substract
19.(3/4)/(1/32)=24
20.(3/4)/(1/14)=21/2
21.(1/2)/(1/72)=36
Answer: 8
Step-by-step explanation:
We know that scale factor = (image)/(preimage).
Substituting in what we have,

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
