Plug g(x) in for every x in f(x) then substitute 4, you’ll get (f o g)(4) = 34
Answer:
7x+12
Step-by-step explanation:
You do 10x-3x since they both have the x variable they can be combined to make 7x and the 12 is left alone.
Answer:
Angle B is 54º.
Step-by-step explanation:
First, find <em>x</em>. Since angle A and angle B are supplementary angles, they add up to 180º.
(7<em>x</em> + 7)º + (4<em>x</em> - 14)º = 180º.
11<em>x</em> - 7 = 180
11x = 187
<em>x</em> = 17.
Now, substitute 17 for <em>x</em> in angle B's equation, (4<em>x</em> - 14).
4(17) - 14
= 68 - 14
= 54º
