The answer would be 101/20
Answer:
Step-by-step explanation:
Consider the quadratic expression
First, find its discriminant:
Note that then
Use quadratic formula to find the roots:
Now, given quadratic expression is equivalent to
Answer:
Cookie=0.5, Apple=1.5, sandwich= 3
Step-by-step explanation:
Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5
10x=5
x=0.5
Answer:
f ∘ g(5) = 47
Step-by-step explanation:
We are given the following functions:
Composite function:
The problem asks their composite function at x = 5. So
We have that f ∘ g(5) = 47
x = original price, or 100%
we know then that it original costs "x", which is the 100%, however is discounted by 40%, so the discounted price is really then 100% - 40% = 60%, and we know that that 60% is $12.
if 60% of the original price is $12, what is "x", the 100%?
