Answer:

5n + 25q = 200 - - - (1)

n = 5q - - - (2)

q = 40

n = 5(40) = 200

Step-by-step explanation:

Number of Nickels = n

Number of Quarters = q

$2.00 = $2 * 100 = 200 cent

Nickel = 5 cent

Quarter = 25 cent

5n + 25q = 200 - - - (1)

n = 5q - - - (2)

5(5q) + 25q = 200

25q + 25q = 200

50q = 200

q = 200/5

q = 40

n = 5(40) = 200

NEED HELP. WILL MARK BRAINLIST. DO NOT SPAM
Tcecarenko [31]

Answer:

  a) x = {-2, 1, 3} are the zeros

  b) y = (x +2)(x -1)(x -3)

  c) y = x^3 -2x^2 -5x +6

Step-by-step explanation:

a) The zeros are the values of x where the graph crosses y=0. Those values are x = -2, x = 1, x = 3.

__

b) If "a" is a zero, then (x-a) is a factor. The factored polynomial is ...

  y = (x +2)(x -1)(x -3)

__

c) This can be multiplied out using the distributive property several times.

  y = (x +2)(x(x -3) -1(x -3))

  = (x +2)(x^2 -3x -x +3)

  = (x +2)(x^2 -4x +3)

  = x(x^2 -4x +3) +2(x^2 -4x +3)

  = x^3 -4x^2 +3x +2x^2 -8x +6

  y = x^3 -2x^2 -5x +6

_____

The supplied graph apparently scales this vertically by a factor of 1/2, since its y-intercept is at (0, 3), not (0, 6).

50 ft
juin [17]

9514 1404 393

Answer:

  1725 ft²

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

Here, the bases are given as 65 ft and 50 ft, and the height is 30 ft. Then the area is ...

  A = 1/2(65 ft +50 ft)(30 ft) = (1/2)(115 ft)(30 ft) = 1725 ft²

You tell the salesman your lawn area is 1725 square feet.
