Answer: ![3yz^2-5y-3z^2+7](https://tex.z-dn.net/?f=3yz%5E2-5y-3z%5E2%2B7)
Step-by-step explanation:
<h3>
The complete exercise is: </h3><h3> "The sum of two polynomials is
![-yz^2 -3z^2-4y + 4](https://tex.z-dn.net/?f=-yz%5E2%20-3z%5E2-4y%20%2B%204)
. If one of the polynomials is
![y - 4yz^2 - 3](https://tex.z-dn.net/?f=y%20-%204yz%5E2%20-%203)
, what is the other polynomial?"</h3>
By definition, the sum is the result of the addition.
According to the information given in the exercise, the polynomial
is obtained by adding the polynomial
and another polynomial.
Then, you can find the other polynomial by subtracting
from
:
![(-yz^2 -3z^2-4y + 4)-(y - 4yz^2 - 3)](https://tex.z-dn.net/?f=%28-yz%5E2%20-3z%5E2-4y%20%2B%204%29-%28y%20-%204yz%5E2%20-%203%29)
So, the steps are:
1. You must distribute the negative sign:
![=-yz^2 -3z^2-4y + 4-y + 4yz^2+ 3](https://tex.z-dn.net/?f=%3D-yz%5E2%20-3z%5E2-4y%20%2B%204-y%20%2B%204yz%5E2%2B%203)
2. Finally, you need to add the like terms:
![=3yz^2-5y-3z^2+7](https://tex.z-dn.net/?f=%3D3yz%5E2-5y-3z%5E2%2B7)
Answer:
x= 1
y= -1
Step-by-step explanation:
y=-2x+1
2x-2y=4
substitute for y
2x-2(-2x+1)=4
reduce
2x+4x-2=4
6x=6
x=1
y= -2(1)+1
y= -1
m I think I'm not really sure sorry if I'm wrong.
Answer:
A) 60
B) 0
C) 150
Step-by-step explanation:
A) P(green) = ⅕
⅕ × 300 = 60
B) since the purple never occured
P(purple) = 0
C) 1000 × (45/300)
150
