Answer:
D
Step-by-step explanation:
R(x) = -x^2+122x+400
6. No, the conclusions wrong because 20 out of 50 peoples favourite is drawing which means 20/50 which equals 0.4 times 100 which is 40% not 60%
7. Yes, the conclusion is right because 5/50 is equal to 0.1 times 100 which is 10%
Since some number added to -11 is 37, we must do 37- (-11), which is 48. Then we check our work and find that 48+-11 is indeed 37. Now we divide 48 by -12, which is -4, multiply by -8 and get a final answer of 32.
First divide by 2
|x+1/4|=3
Then you pick the possible answers
|x+1/4|=3
|x+1/4|=-3
2 3/4 or -3 1/4
