best approximate is 78 F. to find x, count number of hours between 5 am and 2 pm (which is 9). Substitute 9 into the equation and solve. hope this helps!

Step-by-step explanation:

$y = - 0.37 {x}^{2} + 6.15x + 52.3 \\ y = - 0.37 ({9}^{2} ) + 6.15(9) + 52.3 \\ y = - 0.37(81) + 6.15(9) + 52.3 \\ y = - 29.97 + 55.35 + 52.3 \\ y = 77.68$
