Multiple both ratios by a least common denominator
the least common denominator for both is 15
multiply the first ratio by 3/3
9/15=9/15
both are equal because when multiplying by the least common denominator you get the same answer
<span>n(30-14)-25=100
16n=125
n=7.8125 scarves a day, or 8 scarves a day must be sold, in order to make a profit of at least $100.!
I hope this helps!</span>
Answer:
See explanation
Step-by-step explanation:
You are given the function 
The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:
The table is
The inverse function 
has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}
X=-.5, it’s less than 0, and concave up & increasing in this situation are the same.
