Answer:
G=39, F=141
Step-by-step explanation:
Let us set up equations, with G and F as variables.
Since G and F are supplementary, they must add up to 180.
G+F=180
Given the equation, we can set it up too
F = 4 * G - 15
Here, we can solve for this equation by plugging the second equation into the first one with substitution
G+4*G-15=180
simplify and solve
5G=195
G=39
Plug this into the first equation to solve for F:
39+F=180
F=141
We can plug both answers into the second equation to check and find that we are indeed right.
Answer J
if you simplify 98 it’ll give you 9.89...
20 divided by 10 is 2
10 divided by 2 is 5 so it's 2/5
Answer:
Step-by-step explanation:
The nth term of an arithmetic sequence is given by the formula,
We were given that the 9th term is 
.
The sum of the first n-terms is given by the formula,
To find 
, we substitute 
, 
and 
.
The correct answer is D
The solution for this problem would be:
f'(x) = 1 - 1/x^2 = (x^2 - 1)/x^2
is positive where |x| > 1
hence (-inf, -1) and (1, inf) are the regions in which f' is positive and therefore f is increasing.
Therefore, the answer is (-infinity,-1] U [1,infinity).
