<h3>What is an Equation ?</h3>
An Equation is used in determination of unknown variables in an expression .
It is given that
Brian ordered 3 large cheese pizzas and a salad.
The salad cost $4.95
Total amount spend = $47.60
Tip = $5
The amount spend in food is $ 47.60-5
= $42.60
Let the price of Pizza is x then the equation that can be formed to determine the price of pizza is
3x + salad = 42.60
3x + 4.95 = 42.60
3x = 37.65
x = $12.65
Therefore each pizza cost $ 12.65

Answer:
A (Option 1)
Step-by-step explanation:
Hey there!
Functions are basically like machines you put a number into and they give you a new one as an output. This f represents this machine. f(x) represents whatever the output is because it is the x after it has gone through the function machine.
We want to figure out what x is when f(x)=12. Well, we can simply replace f(x) with 12 in the first equation and solve for x!
12=-16x+8
We flip the equation so x is on the left side.
-16x+8=12
We subtract 8 from both sides.
-16x=4
We divide both sides by -16.
x=-1/4
Have a wonderful day! :D
