Based on the graph of the regression model, which is true? the number of weeds is decreasing by a multiplicative rate. the number of weeds is increasing by a multiplicative rate. the number of weeds is decreasing by an additive rate. the number of weeds is increasing by an additive rate.

Based on the graph, the number of weeds decreases exponentially with increasing day after the treatment. However the decrease is not linear which means it does not decrease by a constant rate. Therefore the number of weeds is decreasing by a multiplicative rate.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

d. you cannot tell because there are no values shown.
