Answer:
39
Step-by-step explanation:
This weird notation just means we are going to put one equation inside the other, and then solve.
Makes more sense when you write it like this:
g ( f ( x ) )
To solve, we are going to take the 3, plug it into the f ( x )
g ( f ( 3 ) )
^ This makes it a lot easier to understand what we have to do.
----------------------------------------------------------------------------------------------------------
Ok, so now we evaluate f ( x ) at 3.
4 ( 3 ) - 2
f( x ) = 10
Then we plug it into g ( x )
4 ( 10 ) - 1
= 39
Here's how it looks in total:
4 ( 4 ( 3 ) - 2 ) - 1 = 39
Slightly more complicated, but that's why i broke it down step by step.
Answer:
2(x-6)(x+9)
Step-by-step explanation:
Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35
Step-by-step explanation:
<1 and <2 are adjacent, Supplementary and linear pair angles
