$1000 is taken out of a bank vault each day and nothing is added back. which of the following models this situation?
linear function with a negative rate of change
linear function with a positive rate of change
exponential decay function
exponential growth function

Answer: linear function with a negative rate of change

Step-by-step explanation:

A linear function is of the form where x is a independent variable and y is a dependent variable . Here the dependent variable increase ( or decrease)c with a constant rate of  increase (or decrease).

An exponential functionis a mathematical function of the form where x is a independent variable, and A is a constant called the initial value of the function. Here the dependent variable increase ( or decrease)c with a constant ratio or percentage.

Given: $1000 is taken out of a bank vault each day and nothing is added back.

So the money in the bank vault decreasing by a constant rate of $1000.

Thus, this shows linear function with a negative rate of change models the situation.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
