Jo started from City-A at 9:00am and travelled to City-B which is 720 km away from City-A. If Jo travelled at an average speed of 90 km/h, then at what time in the evening would Jo reach City-B. Use t for time, d for distance, and s for speed (t=d/s). Remember to show your work pls

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

b, i believe, but not sure.
