The answer would be 10x+4y-13 which can also be written as 10x+4y=13.
Answer:
The value of zero is equal to origin
Step-by-step explanation:
Answer:
![y^2 + 8y + 16](https://tex.z-dn.net/?f=%20y%5E2%20%2B%208y%20%2B%2016%20)
Step-by-step explanation:
![(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =](https://tex.z-dn.net/?f=%20%286y%5E2%20%2B%202y%20%2B%205%29%20-%20%285y%5E2%20-%206y%20-%2011%29%20%3D%20)
The first set of parentheses is unnecessary, so it can just be removed.
![= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)](https://tex.z-dn.net/?f=%20%3D%206y%5E2%20%2B%202y%20%2B%205%20-%20%285y%5E2%20-%206y%20-%2011%29%20)
To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.
![= 6y^2 + 2y + 5 - 5y^2 + 6y + 11](https://tex.z-dn.net/?f=%20%3D%206y%5E2%20%2B%202y%20%2B%205%20-%205y%5E2%20%2B%206y%20%2B%2011%20)
Now you combine like terms.
![= 6y^2 - 5y^2 + 2y + 6y + 5 + 11](https://tex.z-dn.net/?f=%20%3D%206y%5E2%20-%205y%5E2%20%2B%202y%20%2B%206y%20%2B%205%20%2B%2011%20)
![= y^2 + 8y + 16](https://tex.z-dn.net/?f=%20%3D%20y%5E2%20%2B%208y%20%2B%2016%20)
Answer:
negative i think :/
Step-by-step explanation:
The solution for the inequality (x − 1)(x + 2) < 0 if x-1 < 0 and x+2 > 0 and x ∈ (-2, 1)
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
(x -1)(x + 2) < 0
The product of (x-1) and (x+2) is less than zero it means:
x-1 < 0 and x+2 > 0 or
x-1 > 0 and x+2 < 0
Solve for first case:
x-1 < 0 and x+2 > 0
x < 1 and x > -2
x ∈ (-2, 1)
Solve for the second case:
x > 1 and x < -2
There will be no intersection region, so no solution in this case.
Thus, the solution for the inequality (x − 1)(x + 2) < 0 if x-1 < 0 and x+2 > 0 and x ∈ (-2, 1)
