FIRST (y x 4 - y x 3 + 2y x 2 + y -1) / (y x 3 + 1)
SECOND (4y-3y+4y+y-1) / (3y+1)
THIRD (6y-1) OVER (3y+1)
Answer:
The new sum have degree = 5
The maximum number of terms of the sum is 6, but it could be less.
Step-by-step explanation:
Given :
Raj writes a polynomial expression in standard form using one variable, a, that has 4 terms and is degree 5.
Let the polynomial: 
Next, Nicole writes a polynomial expression in standard form using one variable, a, that has 3 terms and is degree 2.
The polynomial is: 
Now, adding both polynomials we have:


→ The new sum have degree = 5
→ The maximum number of terms of the sum is 6, but it could be less.
Answer:
Helena is correct.
Step-by-step explanation:
The slope intersept form of the line is
y = m x + c
where, m is the slope and c is the intersept.
The point slope form of the equation is

So, if there are two points are given, the equation of line is found by the point slope form.
So, Helena is correct.
Answer:
I used an Egyptian numeral converter.
Step-by-step explanation:
Sin C = AB / AC
We have AC. We need to calculate AB
ABC is a right triangle. Therefore, AC² = AB²+BC²
82² = AB ² + 80² => AB² = 82² - 80²
AB = 18
Sin C = 18/82 = 9/41
Good luck
