(3 * 10,000) + ( 9* 1,000) + ( 5* 1)
The constant of proportionality (k) equals the total price (y) divided by the number of cans (x).
Step-by-step explanation:
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:

When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
<span>Whenever we are given one function and must calculate a funciton of the funciton, such as g(f(x)) in this case, we simply substitute the second function, f(x) in this case, in the first function, g(x) in this case, wherever the first function has a variable. Therefore,
g(f(x)) = (3x + 2)^2 + 1
g(f(x)) = 9x^2 + 12x + 4 + 1
g(f(x)) = 9x^2 + 12x + 5</span>
The correct is:
![[(-9,3),\:(-5,1),\:(7,-5),\:(4,3)]](https://tex.z-dn.net/?f=%5B%28-9%2C3%29%2C%5C%3A%28-5%2C1%29%2C%5C%3A%287%2C-5%29%2C%5C%3A%284%2C3%29%5D)
The definition of a function is that for every value of
we get one from
.
In the first appears
y
, it is not a function, since it does not meet the definition given above, there can only be one value for x, if there are
or more, called relation.
