Answer:

Add 4K to both sides of the equation

Step-by-step explanation:

The goal is to isolate the variable.

What happens on one side of the equal sign must be done to the other like term on the other side of the equal sign.

k+6=-4k-9

To get rid of the 9 you must add 9 to its like term on the other side of the equation.

You shouldn’t add k to both sides of the equation because k is already positive and to cancel it out you must subtract k. (A variable has an inferred 1) (ex. 1k=k)

You also can’t subtract 4K from both sides of the equation because it is negative so the opposite of the negative would be to add the 4.

The only option that would be correct is the second one:

Add 4K to both sides of the equation because it will cancel out.

If $4,000 is deposited in a bank account paying 4% compounded quarterly, what amount will be in the account after 7 years? How m

pishuonlain [190]

We shall use the equation A = i(1 + r/n)^nt
So we shall plug all of that in so it turns out like this:
A = 4000(1 + 0.04/4)^4 x 7

So then that can be simplified to A = (1.01)^28
and then to A = 4000(1.321)
so then A = 5285.16

Simplify the expression

Vaselesa [24]

To simplify this expression, you have to remember that when a number or a variable is raised to the negative exponent you have to reciprocate the number. In this expression, c^-8 will be reciprocated so it will become part of the numerator. Therefore, the final answer would be 12c^8/d^2.
