Answer:

A.0

Step-by-step explanation:

y=4x²- 9x + 9

The function will intersect the x-axis when  y = 0.

4x² - 9x + 9 = 0

a=4, b= -9, c=9

D=b² - 4ac = (-9)²- 4*4*9=81 - 144= - 63

D= -63, D<0, so the equation

4x² - 9x + 9 = 0 does not have real roots. That means that function    y=4x²- 9x + 9 does not intersect x- axis. So, answer is A. 0.

How to solve the problem 3.2d-4d=2.3d+3
Liula [17]
3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97

or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97

Forty-five roses, plus some number of daffodils and tulips, are blooming in a garden.
stellarik [79]

The maximum number of of bouquets the gardener could have made is 3

<h3>How to find unknown parameter</h3>

Total = 45

let

  • number of daffodils = x
  • number of tulips = y

Roses = 4x

Tulips = 4x + 15

Total = roses + daffodils + tulips

45 = 4x + x + (4x + 15)

45 = 5x + 4x + 15

45 = 9x + 15

45 - 15 = 9x

30 = 9x

x = 30/9

x = 3.33333333333333

Approximately,

x = 3

Let more about equation:
