Answer:
f(-6) = -2
Step-by-step explanation:
plug in k value (-6)
f(-6) = -6/2 + 1
theres two ways to solve for this
one way:
convert the whole number 1 to an improper fraction
f(-6) = -6/2 + 2/2
combine like terms
f(-6) = -4/2
divide -4 by 2
f(-6) = -2
second way:
divide -6 by 2
f(-6) = -3 + 1
combine like terms
f(-6) = -2
either way you get the same answer
use whichever is easiest for you
Step 2 is wrong and i don't know the other question
Answer:
139, I am sorry if I'm wrong

Answer:
(a, b, c) = (30, 50, 55)
Step-by-step explanation:
If we rewrite the ratio of A to B so it has the same number of ratio units as in the ratio of A to C, we have ...
A : B = 3 : 5 = 6 : 10
A : C = 6 : 11
so ...
A : B : C = 6 : 10 : 11
The total number of ratio units is 27. They stand for 135 real units, so each one stands for 135/27 = 5 real units.
Multiplying the last ratio statement by 5, we find the lengths of each of the sides.
A : B : C = 6 : 10 : 11 = 30 : 50 : 55
The side lengths are (a, b, c) = (30, 50, 55).
