Answer:

y = x² - 13x + 36

Step-by-step explanation:

Given the zeros x = 4 and x = 9, then the corresponding factors are

(x - 4) and (x - 9)

The polynomial is then the product of the factors

y = (x - 4)(x - 9) ← expand using FOIL

y = x² - 13x + 36

f(x) = 4x - 2

x = 3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function]:                                                                                f(3) = 4(3) - 2
  2. Multiply:                                                                                                             f(3) = 12 - 2
  3. Subtract:                                                                                                            f(3) = 10

mel-nik [20]

Answer:

25 can.                            

Step-by-step explanation:

Here is the complete question: You are making juice from concentrate. The directions on the packaging say to mix  1 can of juice with 3 cans of water to make orange juice. How many 12 fluid ounces cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?

Given: Ratio to make juice with concentrate:water is 1:3.

As required we need to prepare 200 6 ounce serving of Orange juice.

∴ 200\times 6= 1200\ ounce

Let there be x ounce of concentrate and 3x ounce of water to make 1200 ounce of orange juice.

Now, x+3x= 1200

∴ x= 300 ounce

Next, lets find out how many cans of 12 ounce is required.

\frac{300}{12} = 25\ cans

∴ 25 cans is required to make 1200 ounce of orange juice.
