D and E —> substitute the x or y of the point given into the functions to test if it is correct
Answer:
8.1 gallons of gas
Step-by-step explanation:
240/9=216/x
simplify 240/9 into 80/3,
80/3=216/x
cross product
3*216=80*x
648=80x
x=648/80
x=8.1
Graph 1: Domain = [-6,6]
Graph 1: Range = {-5,-1,0}
Graph 2: Domain = (-4, infinity)
Graph 2: Range = {-4} or [-2, infinity)
Graph 3: Domain = (-infinity, infinity)
Graph 3: Range = [-5, infinity)
Graph 4: Domain = [-5.5, infinity)
Graph 4: Range = (-infinity, infinity)
Answer:
4) 12 different calzones
5) 15 ways
6) 8 outfits
Step-by-step explanation:
When counting the total number of combinations like these situations, multiply the number of choices of each type together
For 4: 3 sizes, times 4 fillings, is 12 different calzones
For a small calzone, there are 4 diffferent fillings to choose from, making 4 calzones,
For a medium calzone, there are 4 differnt fillings, making 4 more for a total of 8,
For a large calzone, there are 4 different fillings, making 4 more for a total of 12
The same logic applies to the other problems
