Answer:</h3>
-y³ -6y²x +30
<h3>
Step-by-step explanation:</h3>
When parentheses are eliminated and the y variable placed first in each term, the expression simplifies to ...
... 15 -7y²x -y³ +y²x +15
Arranging like terms together, we have ...
... -y³ +y²x(-7 +1) +(15 +15)
... -y³ -6y²x +30
_____
The two different 3rd-degree terms can be expressed in either order. I have chosen to list the term with the largest exponent first. The expression could also be written with the same-degree terms in "lexicographical order", meaning the expression would be written ...
... -6xy² -y³ +30
Answer:
This?:
Step-by-step explanation:
To get a double of a number, we add the same number to itself. For example, double of 2 is 2 + 2 = 4. Example: Michelle has 4 marbles and Jane has double the marbles that Michelle has. ... It is easy to remember the numbers that we get by doubling one-digit numbers.
Answer:
-24b - 16c - 36a = -28
Step-by-step explanation:
Given the initial equation of 9a + 6b + 4c = 7 and looking at the second equation of -24b - 16c - 36a, I notice that all of the coefficients of the variables have been multiplied by a factor of -4. Since all of the factors have been multiplied by the same factor, multiplied the answer to the equation by a -4 as well will give us the answer to the problem. Since the original answer is 7, multiplying this answer by a factor of -4: (7)(-4) = -28.
Answer:
5250
Step-by-step explanation:
I’m not quite sure but I believe you are adding the 5% to the original 5000. 5000*(1.05) is 5250
