Step-by-step explanation:
Answer:
f(x)=x−4x2−3x−28 f ( x ) = x - 4 x 2 - 3 x - 2 8 .
Step-by-step explanation:
This is asking you to solve the equation or to graph it.
Answer:
The correct answer is "18k+27r". A further explanation is provided below.
Step-by-step explanation:
The given expression is:
⇒
As we know the identities, such as:
By applying the above identities in the given expression and after opening the brackets, we get
=
=
So if x is the old cost let’s say c is the new cost
So 15%=0.15
0.15(x)=C
