Simplify to a single power of 4: 4^3x4^6

Step-by-step explanation:

4^3 x 4^6

Laws of indices: a^b x a^c = a ^ (b+c)

= 4 ^ (3+6)

= 4^9

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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
