6.) D (x+7)(x+1)
7.) B (x-9)(x+8)
8.) D
9.) A
10.)A
Answer:
3 terms
Step-by-step explanation:
In this problem, we are given an expression of a quadratic function of a single variable x as x² - 3x + 7.
Now, we have to find the number of terms included in the above-given expression.
The expression includes two x terms and one constant term.
Therefore, the whole expression has total ( 2 + 1 ) = 3 terms. (Answer)
Answer:
It is an identity, the proof is in the explanation
Step-by-step explanation:
csc(A)-cot(A)=tan(A/2)
I'm going to start with right hand side
tan(A/2)=(1-cos(a))/(sin(a)) half angle identity
tan(A/2)=1/sin(a)-cos(a)/sin(a) separate fraction
tan(A/2)=csc(a)-cot(a) reciprocal and quotient identities
Slope as an (improper fraction)-9/7, it can’t be simplified
