To figure this out, replace the variables with their given values.
p(a/b) = p(.4/.5)
Then you divide!
.4/.5 = .8
Hope this helps!
The slope is 2/3 and the y intercept is -3
It takes 3 minutes to fill 60L, so it takes 1 hour to fill 1200L.
-9 × 3 - 4² = -27 - 16 = -43
3² + 2² = 9 + 4 = 13
(-9 × 3 - 4²)/(3² + 2²) = -43/13 = -3 4/13
