B) 35
the formula is .5(outer angle - inner angle) = .5(100-30)=.5*70=35
We simply replace a with -9
k(-9) = 4 * -9 - 4
k(-9) = -40

Answer:
n ≤ 5
Step-by-step explanation:
First, we add 14 to both sides. This gets us 5n ≤ 25. Next, we divide both sides by 5. This gets us n ≤ 5. I hope this helps!
Answer:
Ok time to get math on
So this would be D
A non-filled in dot means < or > (depending where arrow is pointing)
A filled in dot means ≤ or ≥ (depending where arrow is pointing)
if an arrow points right, then it would be greater than, if arrow points left.. Then its less than
So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D
A is greater than which is not the answer
B is only equal to which is way off
C is less than but it is equal which is wrong
D is the only right answer
Hope this helps! :)
Answer:
B
Step-by-step explanation:
Remark
I have to represent f(x) as plus +f(x)
I like to show this situation as +f(g(x)) which I think is much clearer.
+f(x) = 5x - 4
Solution
+f(g(x)) = 5(g(x)) - 4 What has happened is that wherever you see an x on the right you put in g(x).
Now on the right, you put whatever g(x) is equal to.
+f(g(x)) = 5(x^2 - 1) - 4
Remove the brackets.
+f(g(x)) = 5x^2 - 5 - 4
And make x = 0
+f(g(0)) = 5*0 - 5 - 4
+f(g(0)) = - 9
