Given: 3x + y = 1. Solve for y. A. y = -3x + 1 B.y = -3x - 1 C.y = 3x - 1

1 answer:

3 0

Y=-3x+1
So the answer is A. All you're doing is moving the 3x to the opposite side, and because your switching the side, you need to switch the sign. So it's a negative 3x after you solve for y. Solving for y(or any letter) is just getting that letter alone on one side of the equal sign.

Answer:

Option 4

The term that represents the amount of time that the money is accruing interest is 'x'.

Step-by-step explanation:

Given : The function below represents the annual interest Alexander earns on a savings account.

$f(x)=500(1+0.02)^x$

To find : Identify the term that represents the amount of time that the money is accruing interest ?

Solution :

The general annual interest formula is $A=P(1+r)^t$

Where, A is the amount

P is the principal

r is the interest rate

t is the time

The annual interest Alexander earns on a savings account is

$f(x)=500(1+0.02)^x$

Comparing with general formula,

t=x

The term that represents the amount of time that the money is accruing interest is 'x'.

Therefore, Option 4 is correct.
