Answer:
I think it's the second one
F(x)=3-2x
g(x)=(1/x)+5
(f/g)(8)
f(8)=3-2(8)
f(8)=3-16
f(8)=-13
g(8)=(1/8)+5
g(8)=5.125, or 41/8
(f/g)(8)=(-13)/(41/8)
(f/g)(8)=-104/41, or -2.536585366
The correct answer for the question that is being presented above is this one: "B. -385." Evaluate the summation of negative 5 n minus 1, from n equals 3 to 12 equals B. -385
-5n - 1 where n = 3 to 12.
n = 3 = -16
n = 4 = -21
n = 5 = -26
n = 6 = -31
n = 7 = -36
n = 8 = -41
n = 9 = -46
n = 10 = -51
n =11 = -56
n = 12 = -61
Total = B. -385
For the first question, x = 4
Answer:
20 degree
Step-by-step explanation:
x + x + 70 = 110 degree (sum of two opposite interior angle equal to the exterior angle formed)
2x = 110 - 70
x = 40/2
x = 20 degree
