Answer:
c is the answer
Step-by-step explanation:
Initial value is f(0) = ???
So when x = 0, y = 3
So
a. so 100-1/10 of 100 or 100-10=90
then second dose minus 10% or 90-9=81
third dose 81 minus 10%=81-8.1=72.9
fourth dose 72.9 minus 10% or 72.9-7.29=65.61
so after 4th dose only 65.61% are left
b. so to get it to 5% you do alot and find that it takes 27 tries to get the percent down to 5.2% and 28 doses to get it to 4.7%
the absolute value is the distance from zero and is marked by the | | signs. The distance from zero for -5 is 5 since it is 5 away from 0. If we rewrite this question, we have 5+3+6 which equals 14. So 14 is your answer.
Answer : 7 pound 4 ounces
1 pound = 16 ounces
x pound = 116 ounces
16x = 116(1) , x= 7.25
116-(7x16) = 4
