Let the weight if a whole pizza be x grams
Then 1/4 of a pizza weighs x/4 grams and one eighth weighs x / 8. The difference is 32 grams so we can make the following equation:-
x/4 - x/8 = 32
x / 8 = 32
Multiplying both sides by 8:-
x = 8*32 = 256
Answer is 256 grams.
What is the series you are referring too?
Y = 7x^2-3
x=7y^2-3
.......................
Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
