Find the value of the greater root of x^2 - 13x + 12 = 0.

a) -12

b) -1

c) 1

d) 12

The largest root of this equation is 12

Step-by-step explanation:

To find this, first factor the equation.

x^2 - 13x + 12 = 0

(x - 12)(x - 1) = 0

Now set each parenthesis equal to 0 to get the roots.

x - 12 = 0

x = 12

x - 1 = 0

x = 1

The larger of those two is 12 and that is the answer.

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

answer:

c) the x-coordinate of the center of the circle increases by 3
