B. 82 because complementary angles equal 90˚ combined and 90-8=82
Answer:
36.3 percent
Step-by-step explanation:
First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665
The first one is 23.430, I don't have time to help with the second part of the question, but good luck! :)
