An=2n-3 find the first five terms of the sequence

-1 , 1 , 3 , 5 , 7

Step-by-step explanation:

An = = 2n - 3

n = 1;       A1 = 2*1 - 3  =  2 - 3 = -1

n =2;      A2 = 2*2 - 3 =  4 - 3 = 1

n = 3;     A3 = 2*3 - 3 =  6 - 3 = 3

n= 4;      A4 = 2*4 - 3 =  8 - 3 = 5

n = 5;     A5 = 2*5 - 3 = 10 - 3 = 7

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
