Answer:
y - 9 = 1/3 (x+8)
Step-by-step explanation:
point slope form is y - y1 = m (x - x1)
114.50 if you add everything together and then subtract 67.50 you’ll get your answer
Answer:
w = 2, EF = 30 , FG = 42
Explanation:
We have EF = 5w + 20 and FG = 7w + 28
Since these points E, F and G are col-linear points we have.
EG = EF + FG
And given that EG = 72
So, EF+EG = 72
5w + 20 + 7w + 28 = 72
12w + 48 = 72
12 w = 24
w = 2
So EF = 5w + 20 = 5x2 + 20 = 30
FG = 7w + 28 = 7x2 + 28 = 42
If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.
So,
1.



are polynomials.
2.

y
2 + s

are all polynomials.
3.
If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.
Hence,
is a cubic trinomial.
4.
The highest power is the degree.
Hence, degree of the polynomial is 2 + 4 = 6.
