Simplify 0.5(1.1-2x) +2.4x-2.10

Mathematics
1 answer:
Novosadov [1.4K]2 years ago
5 0

Answer:

1.4x - 1.55

Step-by-step explanation:

We have to simplify the expression as 0.5(1.1 - 2x) + 2.4x - 2.1

Now, 0.5(1.1 - 2x) + 2.4x - 2.1

= 0.5 × 1.1 - 0.5 × 2x + 2.4x - 2.1 {Using the distributive property of multiplication}

= 0.55 - x + 2.4x - 2.1

= 1.4x - (2.1 - 0.55)

= 1.4x - 1.55 ( Answer )

The temperature was 21 then it got to -3 how much it drop
dimulka [17.4K]
At first the temperature will have to drop to a 0 whether it’s Fahrenheit or Celsius so that’s 21 degrees. To get to -3, that’s an extra three degrees dropped. So 21 plus 3 equals 24 degrees dropped.

Write the function into standard form <br><br> f(x)=2(x-3)^2-4
Travka [436]

Answer:

f(x) = 2x² - 12x + 14

General Formulas and Concepts:

<u>Algebra I</u>

  • Expanding by FOILing
  • Combining like terms
  • Standard Form: f(x) = ax² + bx + c
  • Vertex Form: f(x) = a(x - h)² + k

Step-by-step explanation:

<u>Step 1: Define function</u>

Vertex Form:   f(x) = 2(x - 3)² - 4

<u>Step 2: Convert to Standard Form</u>

  1. Expand by FOILing:                    f(x) = 2(x² - 6x + 9) - 4
  2. Distribute 2:                                 f(x) = 2x² - 12x + 18 - 4
  3. Combine like terms:                    f(x) = 2x² - 12x + 14

And we have our final answer!
