By driving 8 mph faster than Bob, John can make a 230 mile trip in one half hour less.How fast does Bob drive on the trip? Round
aivan3 [116]

Answer:

  57 mph

Step-by-step explanation:

Let b represent Bob's speed on the trip. Then his time is ...

  time = distance/speed

  Bob's time = 230/b

Then John's speed is b+8, and his time is ...

  John's time = 230/(b+8)

The difference of their times is 1/2 hour:

  Bob's time - John's time = 1/2

  230/b -230/(b+8) = 1/2 . . . substitute the expressions for time

  460(b+8 -b) = b(b+8) . . . . . multiply by 2b(b+8)

  b^2 +8b -3680 = 0 . . . . . . .put in standard form

  (b +4)^2 -3696 = 0 . . . . . . . add 16-16 to complete the square

  b = -4 +√3696 ≈ 56.795 . . . solve for positive b

Bob's drove about 57 mph on the trip.

What is the leading coefficient in this expression? 6x^2 + 3x +7
zzz [600]

In functions, the coefficient is the number that multiplies the variables, for example, for 5y, the coefficient is the number "5"

The "leading coefficient" refers to the number that multiplies the greater term of the expression (i.e. the term with the largest exponent), and if the terms are ordered from greatest to least, it corresponds to the coefficient of the first term.

So for the expression

6x^2+3x+7

The first and the term with the largest exponent is:

6x^2

Where "6" is the coefficient of the term and thus the "leading coefficient" of the expression.
