If u = –9 and v = –5, what is the value of u – v?

-4

Step-by-step explanation: a subtraction sign with a negative number always turns that number into a positive number therefore the problem would be -9 + 5 which equals -4

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
