Answer:

a) 10 y = x

b) 8.5 min

Step-by-step explanation:

a) x - axis = distance

y - axis = time

the line passing through points (10,1) (20,2) (30,3).......

line equation is y - y1 = m (x - x1)

m = (y2 -y1) / (x2 - x1)

= (2 - 1) / (20 - 10)

m = 1/10

y - 1 = 1/10 * (x - 10)

10(y - 1) = x - 10

10y - 10 = x - 10

10y = x

here x represents distance

y represents time

b) for distance of 85 inches

time =

10 * time = 85

time = 8.5 min

Alja [10]
<span>Given that Devorah is filling a pool with a hose. The volume.H. In liters, of water coming out of the hose in .m.minutes is given by the function H(m)=17.4m. However it is a sunny day, and water is also evaporating from the pool. Therefore,the volume ,V, in liters, of water in the pool m minutes after devorah started filling it is given by V(m)=17m.

  IfE be the volume of water, In Liters ,that has evaporated from the pool m minutes after devorah started filling it .

The formula for E(m) in terms of H(m) and V(m) is given by

E(m) = H(m) - V(m)

And

The formula for E(m) in terms of m is given by

E(m) = 17.4m - 17m = 0.4m</span>
