Answer: -12x^2y\ and\ 4x^2y


Step-by-step explanation:

Given monomial: 3x^2y, here deg of x is 2 and deg of y is 1

From the options, we have -12x^2y\ and\ 4x^2y polynomials [with deg of x is 2 and deg of y is 1]which are like to the given polynomial.

We know that if we add like monomials, then we get result as mnomila.

Rest of other monomials are unlike to the given monomial, which will result into  binomial.

1)3x^2y+3xy\\2)-12x^2y+3x^y=-9x^2y\\3)2x^2y^2+3x^2y\\4)7x^y+3x^2y\\5)-10x^2+3x^2y\\6)4x^2y+3x^2y=7x^2y\\7)3x^3+3x^2y

Answer:

-12x^{2}y and 4x^{2}y

Step-by-step explanation:

We are given the term 3x^{2}y.

<em>It is known that, 'A monomial is an algebraic expression consisting of one term'.</em>

So, we add the given options to 3x^{2}y.

1.  3x^{2}y+3xy=3xy(x+1)

2. 3x^{2}y-12x^{2}y=-9x^{2}y

3.  3x^{2}y+2x^{2}y^{2}=x^{2}y(3+2y)

4.  3x^{2}y+7xy^{2}=xy(3x+7y)

5.  3x^{2}y-10x^{2}=x^{2}(3y-10)

6.  3x^{2}y+4x^{2}y=7x^{2}y

7.  3x^{2}y+3x^{3}=3x^{2}(y+x)

As, we can see that only option 2 and 6 results in an expression having one term.

Thus, adding -12x^{2}y and 4x^{2}y to 3x^{2}y results in a monomial.

To reduce wear and tear on the family vehicle, you decide to rent a car. Happy Harry’s Rentals has a $500 fee for any rental up
yan [13]

Let's use 8 days as the maximum time we are going to be renting the car.

Putting that into the equation means, 500$ for Harry's Rentals and Smilin' Sam's at $600.

Therefore, Happy Harry's Rentals are better for the 7th and 8th days while Smiling Sam's are the better from day's 1 to 6.

Work:

500$ is a fixed value so it doesn't change (constant)

200 + 50x

x = days

8 days = 8x

200 + 50(8)

200 + 400 = 600

If you are one of the first 100 people to join a new health club, you are charged a joining fee of $49. Otherwise, you are charg
Drupady [299]

Answer:

a) Total cost = 49 + 38.75m

b) Total cost = 149 + 38.75m

c) The graphs of the lines are parallel and both has slope of - 2.5

d)Difference in total cost = $132.5

Step-by-step explanation:

Total cost , TC = Initial membership fee + monthly charges

a) TC = 49 + 38.75m

b)TC = 149 + 38.75m

d) 149 + 38.75(6months) = 381.5

49 + 38.75(12months) = 514

Difference in total cost = 514 -381.5 = $132.5

To find the mean you must add up all the numbers you have together and then divide the buy the amount of numbers you added. When you add these numbers up you get 30, and we have 5 numbers here, when we divide 30 by 5 we get 6. So, Tara is correct in saying that the mean is 6.
