A plant is 5cm tall and growing at a rate of 3cm a month. What equation is right? 1. y=5x+3
2. y=5-3x
3. y=3x+5

y=3x+5

Step-by-step explanation:

The plant starts at 5cm so +5 is the starting height, It grows at 3cm a month making 3x the growth rate. so 3x+5 is the height of the plant every month.

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
