Because y=3x has a coefficient of 3 and y=x3 does not have a coefficient because the variable is the first terms. therefore it is not an exponential function.
The volume of the tuna can is 663.66 cm^3.
Hope that helps!
Because they will always be divisible by 5
So if m=4a+2c is your equation then all you have to do is plug in the numbers.
So you then get m=4(25)+2(7), for 25 adults and 7 children.
Then you solve. m=100+2(7)
m=100+14
m=114
So Frank will need 114 Meatballs for the party of 25 adults and 7 children
Hope this helps! And if you need anything else just ask :)
