Answer:

12

Step-by-step explanation:

We input 2 into each function:

w(2) = 3(2) - 2 = 4

v(2) = 2(2) + 7 = 11

k(2) = -6(2) - 7 = -19

Then we place our answers in w - v - k

(4) - (11) - (-19)

= 4 - 11 + 19

= 12

John has $4000 in his savings account.each month he withdraws $70 from his account which is the type of function that models thi
r-ruslan [8.4K]

Answer:

y = 4000 - 70x

Linear function.

Step-by-step explanation:

Let x = number of weeks.

In 1 week, he withdraws $70.

That means -70 in 1 week.

After the second week, he will have withdrawn 2 times $70, or

-70 × 2

After 3 week, he will have withdrawn -70 × 3

After x weeks, he will have withdrawn $70 × x,or simply -70x.

He starts with 4000, so after x weeks, he has 4000 - 7x.

Let y = the amount of money at week x.

The equation is

y = 4000 - 70x

This is a linear function.
