Answer:
a) 41
b) -31
c) 25/3
Step-by-step explanation:
The instructions explain what a function is pretty clearly.
Basically, whatever is in the parentheses next to the , you plug in to the expression that is the function.
ex:
Okay, onto the problems:
a)
First, plug in 14, since that is given:
and solve.
So, 41 is the answer to a.
b) Do the same thing you did in problem a. Plug in the number inside the parentheses and solve.
-31 is the answer to b.
c) For this problem, you have to do a bit of algebra.
First, take the base function f(x):
Then, set f(x) = 24:
and solve by isolating x.
25/3 is the answer to c.
Answer:
x = 4
Step-by-step explanation:
the segment inside the triangle is an angle bisector and divide the opposite side into segments that are proportional to the other two sides, that is
=
=
=
( cross- multiply )
2x = x + 4 ( subtract x from both sides )
x = 4
