Answer:
first what the full question and if 25*16/2=200
Step-by-step explanation:
Answer: 5x-7
Step-by-step explanation:
A:
(f+g)(x)=f(x)+g(x)
(f+g)(x)=4x-5+3x+9
(f+g)(x)=7x+4
B:
(f•g)(x)=f(x)•g(x)
(f•g)(x)=(4x-5)(3x+9)
(f•g)(x)=12x^2-15x+36x-45
(f•g)(x)=12x^2+21x-45
C:
(f○g)(x)=f(g(x))
(f○g)(x)=4(3x+9)-5
(f○g)(x)=12x+36-5
(f○g)(x)=12x+31
<1 and <2 are supplementary angles. They add up to 180 degrees.
92 and <2 are corresponding angles, they have the same measure.
So,<2 = 92 degrees
180-92= 88 degrees
<1= 88 degrees
I hope this helps!
