Jen has collected information about the students in her class and the month they were born.
which of the following statements would be true about this information?
it is both a relation and a function.
it is a relation but not a function.
it is not a relation, but it is a function.
it is neither a relation nor a function.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

if you was gonna solve for a, a is a   < -12

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
