Answer:

8x^2 + 24x - 14

Coefficients:- a =  8, b = 24 and c = -14.

Step-by-step explanation:

(4x - 2)(2x + 7)

= 4x(2x + 7) - 2(2x + 7)

= 8x^2 + 28x - 4x - 14

= 8x^2 + 24x - 14

Coefficient a =  8, b = 24 and c = -14.

Neporo4naja [7]

Answer:

  y = one-half x + three-fourths

Step-by-step explanation:

The 2-point form of the equation of a line can be used for starters.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (11/12 -19/20)/(1/3 -2/5)(x -2/5) +19/20 . . . . fill in given values

  y = ((55 -57)/60)/((5 -6)/15)(x -8/20) +19/20 . . simplify a little

  y = (-1/30)/(-2/30)(x -8/20) +19/20 . . . . . . . . . . and a little more ...

  y = 1/2x -4/20 +19/20

  y = 1/2x +15/20

  y = 1/2x +3/4 . . . . line in slope-intercept form
