Urgent. Factor out the GCF from the polynomial. a^7b^9-a^5b^4+a^4b^6-a^4b^4. Please show work. Thanks.

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

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
