How many solutions are in this problem y=2x^2+9x

Also if u could, could u tell me if I’m correct if I said the discriminate is 81?

answer: i don't understand. what are the options

step-by-step explanation:

i got 10.28 but that rounds up to 10.3

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
