Question

I need help answering this question

Answer 1

Answer:

a = 80

b = 3/4

the general equation is;

y = 80•(3/4)^x

Step-by-step explanation:

Here, we want to get the values of a and b

We are going to use the two points given

(0,80) and (1,60)

So we have this as;

for the first point;

80 = a•b^0

anything raised to power of 0 is 1

Thus;

80 = a * 1

a = 80

for the second point;

60 = 80 * b^1

60 = 80b

b = 60/80

b = 3/4

So we have the general equation as;

y = 80•(3/4)^x
