Answer:

Walt = 48  years

Ralph =  45 years

Henry = 41 years

Step-by-step explanation:

We know that ​Walt is 3 years older than Ralph so we can write,

Walt = 3 + Ralph        eq. 1

We also know that Ralph is 4 years older than Henry so we can write,

Ralph = 4 + Henry      eq. 2

It is given that Walt's age is 48 years so substitute it into eq. 1

Walt = 3 + Ralph

48 = 3 + Ralph

Ralph = 48 - 3

Ralph = 45 years

Now substitute the age of Ralph into eq. 2

Ralph = 4 + Henry

45 = 4 + Henry

Henry = 45 - 4

Henry = 41 years

Therefore,

Walt = 48  years

Ralph =  45 years

Henry = 41 years

Verification:

Walt = 3 + Ralph        eq. 1

48 = 3 + 45  

48 = 48 satisfied

Ralph = 4 + Henry      eq. 2

45 = 4 + 41

45 = 45 satisfied

Answer:

Ralph is 45 and Henry is 41

Step-by-step explanation:

if Walt is 48 to find Ralph you subtract 3 because Walt is 3 tears older than Ralph.

to find Henry you subtract 4 from Ralph and get 41

Answer:

A:

The decreasing value of car 1 can be represented by an exponential function and car 2 by a linear function

B:

Car 1: f(x) = 18500(0.94)^{x}

Car 2: f(x) = 18500 - 1000x

C:

Car 1 would be $10600.40 after 9 years

Car 2 would be $9500.00 after 9 years

There is a significant difference of $1100.40 in value.

Step-by-step explanation:

f(x) = ar^{x}\\f(0) = a = 18500\\f(x) = 18500r^{x}\\f(1) = 18500r = 17390\\r = \frac{17390}{18500} = 0.94\\f(x) = 18500(0.94)^{x}
