An equation is formed when two equal expressions. The cost of serving a pancake will cost $4.25.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that your total bill amount is $11.50. Also, you give a tip of 15% of your bill. Therefore, if the amount of the bill is assumed to be x then the total bill amount can be written as,
Total bill amount = Bill amount + 15% of the bill amount
$11.50 = x + 0.15x
11.50 = 1.15x
x = $11.50 / 1.15
x = $10
Therefore, the bill amount for the food was $10.
The cost of the fruit cup is $1.50, while the order was two servings of Pancakes and a fruit cup. Therefore, if the cost of a serving of pancake is assumed to be 'c'. Then we can write,
Cost of fruitcake + Cost of two pancakes = $10
$1.50 + 2c = $10
2c = $10 - $1.50
2c = $8.5
c = $8.5/2
c = $4.25
Hence, the cost of a serving of pancakes will cost $4.25.

An absolute value function has a graph that is V shaped.
The domain is the input (x) value, which can be any real number, so the domain is (-∞,∞)
The range starts at the vertex and goes to infinity.
To find the vertex, set the absolute value part of the equation to 0 and solve for x:
x+3 = 0. x = -3
Now replace x with -3 and solve the full equation:
|-3 +3|-1 = -1
The vertex becomes (-3,-1)
The range is the output value ( Y) , so the range would be [-1,∞)
See attached picture for graph:
Answer:
The graph would be something like this.
Step-by-step explanation:
The domain and range would be (-∞, +∞)
This is because, the function f(x) is valid for any of the values between (-∞, +∞)
Hope it helps.
