Set up a proportion:
The numerator represents fluid ounces of milk, and the denominator represents milligrams of calcium.
Simplify the first fraction to make multiplication easier:
Cross multiply the fractions:
Divide both sides by 135 to get x by itself:
2.1 fluid ounces of milk provide 72.5 milligrams of calcium.
Y = 5.50x + 21...where x is the number of months and y is the total cost
function notation is basically subbing in f(x) for y
so ur rule in function notation is : f(x) = 5.50x + 21 <==
Answer:
b = -8
Step-by-step explanation:
crossmultiply
Here it is…
Simplifying
C = 25h + 50
Reorder the terms:
C = 50 + 25h
Solving
C = 50 + 25h
Solving for variable 'C'.
Move all terms containing C to the left, all other terms to the right.
Simplifying
C = 50 + 25h
1. (x+3) (x+8), 2. (x-9)^2
