All you have to do here is add 209 to both sides to get -8x² - 9x + 209 = 0
From there I'm sure you can work it out :)
For the first one the domain and range are all real numbers and for the second one the domain is: 0
$5.00 plus $1.25 equals $6.25 then that times 2 would equal $12.50 so his allowance was $12.50
Three consecutive integers that add up to 27 are 8, 9, and 10
Hope this helps =)
