f(X)=3/x-1,g(x)=2/x
g.f(-5)=g(f(-5))=g(-3/5-1)=g(-3-5/5)=g(-8/5)=2×(-5/8)=-5/4

Answer:
it a 90 degree angle hope this helps:)
Step-by-step explanation:
Answer:
Step-by-step explanation:
3π/2 is equivalent to 270°. The "opposite side" for this angle is -2; the adjacent side is 0, and the hypotenuse is 2.
Thus, sin 3π/2 = opp/hyp = -2/2 = -1, and
cos 3π/2 = adj/hyp = 0/2 = 0.
Answer: n=58
Step-by-step explanation:
7(n-7)=3(2n+3)
We move all terms to the left:
7(n-7)-(3(2n+3))=0
We multiply parentheses
7n-(3(2n+3))-49=0
We calculate terms in parentheses: -(3(2n+3)), so:
3(2n+3)
We multiply parentheses
6n+9
Back to the equation:
-(6n+9)
We get rid of parentheses
7n-6n-9-49=0
We add all the numbers together, and all the variables
n-58=0
We move all terms containing n to the left, all other terms to the right
n=58
