The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5

Answer:
24 hours
Step-by-step explanation:
It appears that the score (s) is related to the number of hours (h) by ...
s = 30 +(10/4)h
So, for a score of 90, the number of study hours needs to be ...
90 = 30 +2.5h
60 = 2.5h
60/2.5 = h = 24
Jesse needs to study 24 hours to get a score of 90.
