4) Find the solutions, or roots, to the following functions by factoring: a. F(b) = b2 + 3b - 4 b. y = 4x2 - 100 c. y = 2x2 - 10x - 48 d. f(x) = x2 – 6x – 12

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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

12 cups   is the answer
