Answer:

x = 3/4 or x = 0.75

Step-by-step explanation:

y=2x²-3x+4

y'=4x-3 = 0

x = 3/4 .... answer

or

x = - b/2a    ...y=ax²+bx+c

x = - (-3)/(2*2) = 3/4

GenaCL600 [577]

Answer:

see below

Step-by-step explanation:

1.)

(0, 4)

(1, 7)

\frac{7-4}{1-0} = 3

y = 3x + b

(4) = 3(0) + b

b = 4

y = 3x + 4

Rate of change: 3       initial value: 4

2.)

(0, -5)

(1, -3)

\frac{-3-(-5)}{1-0} = 2

y = 2x + b

(-5) = 2(0) + b

b = -5

Rate of change: 2        initial value: -5

Sam wants to make 4 gallons of vegetable bean soup. The recipe below makes 13 gallon of soup. Help Sam make his grocery list for
Zolol [24]

The proportion of the recipe required to make the grocery list is obtained from the recipe for the beans soup.

The grocery list is therefore;

  • <u>15 cups of honey beans</u>
  • <u>9 cups carrots</u>
  • <u>12 cups cherry tomato</u>
  • <u>192 oz. vegetable broth</u>
  • <u>10.5 cup turnips</u>
  • <u>6 teaspoon salt</u>
  • <u>8 cups potato onions</u>
  • <u>1.25 teaspoons thyme</u>
  • <u>12 teaspoons garlic</u>

Reason:

Amounts of beans soup Sam wants to make = 4 gallons

<em>The recipe for the beans soup is as follows as obtained from an online home work document are</em>;

<em>Vegetable Bean Soup that Serves 4 with volume of 0.</em>\overline 3<em> gallons</em>

<em>1.25 cups of honey beans</em>

<em>0.75 cup carrots</em>

<em>1 cup cherry tomato</em>

<em>16 oz. vegetable broth</em>

<em>0.875 cup turnips</em>

<em>0.5 teaspoon salt</em>

<em />0.\overline 6<em> cup potato onions</em>

<em>0.125 teaspoon thyme</em>

<em>1 teaspoon garlic</em>

The amount of each ingredient Sam needs is given by the ratio of amount of soup Sam wants to make and the given amount of soup made by the ingredients as follows;

Multiple \ of \ ingredient \ amount = \dfrac{4}{0. \overline 3} = \dfrac{4}{\dfrac{1}{3} } = 4 \times 3 = 12

Therefore, Sam has to buy twelve times the amount of each ingredient as follows;

Vegetable Bean Soup that Serves 4 with volume of 0.\mathbf{\overline 3} gallons

12 × 1.25 = 15 cups of honey beans

12 × 0.75 = 9 cups of carrots

12 × 1 = 12 cups of cherry tomato

12 × 16 = 192 oz. vegetable broth

12 × 0.875 = 10.5 cup turnips

12 × 0.5 = 6 teaspoon salt

12 × 0.\overline 6 = 8 cups of potato onions

12 × 0.125 = 1.25 teaspoons thyme

12 × 1 = 12 teaspoons garlic

The grocery list is therefore;

  • 15 cups of honey beans
  • 9 cups carrots
  • 12 cups cherry tomato
  • 192 oz. vegetable broth
  • 10.5 cup turnips
  • 6 teaspoon salt
  • 8 cups potato onions
  • 1.25 teaspoons thyme
  • 12 teaspoons garlic
