I just need help with 4 questions please

OpenStudy (lurker):

y is equal to those 2 things so you can equate them together

OpenStudy (lurker):

\[3.25= - 0.5{x^2} + x + 6\]

OpenStudy (anonymous):

okay

OpenStudy (lurker):

simplify it to \[0= - 0.5{x^2} + x + 2.75\] now you can use the quadratic equation to find the roots
