What is the answer ?

Answers

-7y -3y +2 = -8y-8

-10y +2 = -8y-8

-10y +8y = -8 -2

-2y = -10

2y = 10

y = 10/2 = 5

Answer:

y =  -5/6

Step-by-step explanation:

7y - 3y + 2 = -8y - 8

12y + 2 = -8

12y = -10

y = -10/12 = -5/6

at the car wash fundraiser jenna's team washed 14 cars in 45 minutes. if they keep up at that rate, how many cars can the team wash in 2.5 hours? how did you get the answer

Answers

You can write it as a proportion and then solve the proportion. 
(2.5 hours is 150 minutes)
14 cars          x cars
--------------- = -------------------
45 minutes    150 minutes

Then solve.

x=46.6666666
So that is about 47 cars

What is the additive inverse of the polynomial? -7y^2+x^2y-3xy-7x^2

Answers

Answer:

Additive inverse is  (7y² - x²y + 3xy + 7x²).

Step-by-step explanation:

Let the additive inverse of the given polynomial be Y.

Therefore as per definition of additive inverse of any polynomial the addition of a polynomial and additive inverse of any polynomial is always zero.

So Polynomial + additive inverse polynomial = 0

(-7y² + x²y - 3xy - 7x²) + Y = 0

Y = -(-7y² + x²y - 3xy - 7x²) = (7y² - x²y + 3xy + 7x²)

So the additive inverse of the polynomial will be (7y² - x²y + 3xy + 7x²).

Answer:

The answer is A

Step-by-step explanation:

The additive inverse is basically the opposite symbol for the numbers.

So, therefore:

What is the additive inverse of the polynomial?

-7y^2 + x^2y - 3xy - 7x^2

The answer to this would be

7y^2 - x^2y + 3xy + 7x^2

What does at least and at most mean?

Answers

At least means the minimum or the lowest baseline.

For example: A candy bar costs between 1-2$  so if there is a boy asking money from his mom, he needs to ask for at least 1$

At most means the maximum amount or the highest amount or ceiling amount. 

For example: To buy a shirt online, I need at least $10 but at most, it should cost $25
