Which polynomial is in standard form? 1 + 2x - 8x + OX
O 2x2 +6x3-9x+ 12
6x3 + 5x-3x2 + 2
2x3+4x2 - 7x+5

last option is correct because the standard form of polynomial means the arrangement of power in descending order

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
