Answer:
3x^2-4x+2
Step-by-step explanation:
Just took it
Trust me
"X is partly constant and partly varies as y"
---> x = ky + p
when y=2,x=30 ---> 30 = 2k + p
when y=6,x=50 ---> 50 = 6k + p
subtract: 20 = 4k
k = 5
sub back in the first: 30 = 10+p
p = 20
x = 5y + 20
now you can answer B
notice this is just a variation of y = mx + b
It would be 96 have a great night
