Taxi a charges $0.20 per mile and an initial fee of $4. taxi b charges $0.40 per mile and an initial fee of $2. write an inequality that can determine when the cost of taxi b will be greater than taxi a. a) 0.20x + 4 > 0.40x + 2 b) 0.20x + 4 < 0.40x + 2 c) 0.20x + 0.40x > 4 + 2 d) 0.20x + 0.40x < 4 + 2

B.

Step-by-step explanation:

let x denotes the number of mile taxi runs.

Given : Taxi A charges $0.20 per mile and an initial fee of $4.

i.e. the expression to show total charge by Taxi A will be :

Taxi B charges $0.40 per mile and an initial fee of $2.

i.e. the expression to show total charge by Taxi B will be :

Now, the inequality that can determine when the cost of Taxi B will be greater than Taxi A will be :-

Hence, B is the correct answer.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
