The equation for the line of reflection
Taking points A and A' as a point of reference:
and
First, calculate the midpoint (M)
Calculate the slope (m)
The midpoint of a reflection is always perpendicular to the points being reflected.
So, the slope of is:
The equation is then calculated as:
Where:
Hence, the equation of line of reflection is:

Relationship between gallon and ounces
-- (1)
-- (2)
Multiply 2 by 2
--- (3)
The expressions in (1) and (3) are equivalent to 8 cups;
They can be combined to give:
Multiply both sides by 2
Answer:
849
Step-by-step explanation:
To get the better deal, you should find the selling prices for a single tacos in both cases and compare the amounts.
In the first one, 10 tacos for $8.49
This means 1 tacos sells for $8.49/10 = $0.849
In the second one, 6 for $5.40, this means for a single tacos, the selling price is $5.40/6 =$0.9
The better deal is the first one that sells one taco for $0.849 compared to the second one that sells one tacos for $0.9
Rate of change is Rise over run=3/36=1/12 inches
