That would be:-
x^2 + x - 72 = 0
(x + 9)(x - 8) = 0
smallest number is 8
it's option e because half of 6 is 3, and by dividing y and x all by two, then it must be divisible by 3

Answer:
- y = 32.1x +779.9
- 1165 cases in 2010
Step-by-step explanation:
A suitable statistics calculator can tell you the coefficients of the linear regression equation. In the attached, we put the given x- and y-values into a table and asked for the best fit equation. Rounded to tenths, the equation is ...
y = 32.1x +779.9
The year 2010 is 12 years after 1998, so we can find the desired projection using x=12.
y = 32.1×12 +779.9 = 385.2 +779.9 = 1165.1
The number of cases is projected to be 1165 in 2010.

We wonder if using the button "Open Statistics Calculator" will let you solve this question yourself.
Added gallons: 23.50÷1.25=18.8
All of the gases: 5+18.8=23.8
now the total distance: 23.8*27=642.6≈643 miles.
I hope this helps!
