A total of 321 adults and children are at a movie theater. There are 216 more adults than children in the
theater. If a represents the number of adults and b
represents the number of children, which system of
equations could be used to find the number of adults
and the number of children in the theatre?
O a+b = 321
a= 216b
O a+b=321
b= 2160
a + b = 321
a = b + 216
D a + b = 321
b= a + 216

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

if you need just tell me and i will come to the rescue.

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
