The line that is parallel is DE
Answer:
All of them are polynomial functions
Step-by-step explanation:
Remember that a polynomial function of x is a function whose value f(x) is always equal to 
for a fixed n≥0 (the degree of f) and fixed coefficients 
For example, 
is a polynomial function, but 
is not because 
is not a nonnegative power of x. Another example of a non-polynomial function is 
.
f(x)=4⋅11x is polynomial with degree 1 and 
. For the same reasons, f(x)=3⋅18x and f(x)=10⋅17x are polynomial functions.
f(x)=−4x³−4x²+5x+1 is a polynomial function of degree 3 with 
. and f(x)=−2x−1 is a polynomial function of degree 1 and coefficients 
.
Answer:
1. x > 9
2. n < 5
3. b > 2
4. p < 4
5. p < -2
6. m > 0
Step-by-step explanation:
1.
x - 2 - 2 > 5
x - 4 > 5
x > 5 + 4
x > 9
2.
5 + n < 2 x 5
n < 10 - 5
n < 5
3.
50b > 100
b > 100 : 50
b > 2
4.
-5 + p + 2 < 1
p < 1 + 3
p < 4
5.
p + 6 + 8 < 12
p + 14 < 12
p < 12 - 14
p < -2
6.
80m - 64 - 2 > -66
80m > -66 + 66
m > 0:80
m > 0
We write f(x) in terms of y I.e y=7x-1/2.
Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.
Make x the subject, x=2y+1/14,
Thus the inverse f(x)=2x+1/14
