Answer:

The correct answer is Option 3: 12y

Step-by-step explanation:

A polynomial term is usually made of a variable and a co-efficient.

Like terms are those terms that have the same variables i.e. x and 44x are like terms.

Given expression is:

6y-2y+8y

All the terms have only y which means that all three terms are alike.

The coefficients of like terms are added or subtracted according to their sign.

6y-2y+8y = 12y

Hence,

The correct answer is Option 3: 12y

Which is the equation of a circle with its center at (-4,2) and a radius of 4?
Snowcat [4.5K]

Answer:

(x +4)^2 + (y-2)^2 = 16

Step-by-step explanation:

We can write the equation for a circle with the formula

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

We know the center is at (-4,2) and the radius is 4

(x- -4)^2 + (y-2)^2 = 4^2

(x +4)^2 + (y-2)^2 = 16

Jill invested $500 in an account with a compound interest rate of 6%. cheryl invests $600 in an account with a compound interest
34kurt

The time taken by Jill and Cheryl to double their money is 12 years and 18 years respectively.

<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

Jill invested $500 in an account with a compound interest rate of 6%.

Cheryl invests $600 in an account with a compound interest rate of 4%.

The number of years each doubles their money. Using the relation of 72.

\rm t  = \dfrac{72}{r}

where r is the interest rate and t be the time

The time for the Jill will be

\rm t = \dfrac{72}{6}\\\\t = 12\\

The time for the Cheryl will be

\rm t = \dfrac{72}{4}\\\\t = 18\\
