Answer:

D

Step-by-step explanation:

Consider the equation:

\dfrac{3}{4}(24-16x)=-\dfrac{2}{3}(18x-27)

Use distributive property in both sides:

\dfrac{3}{4}\cdot 24-\dfrac{3}{4}\cdot 16x=-\dfrac{2}{3}\cdot 18x+\dfrac{2}{3}\cdot 27\\ \\3\cdot 6-3\cdot 4x=-2\cdot 6x+2\cdot 9\\ \\18-12x=-12x+18

Separate terms with x into the left part and terms without x into the right part:

-12x+12x=18-18\\ \\0=0

Since you get true equality 0 = 0, the equation is true for all real values of x. So, the equation has infinitely many solutions.

F(x)=−10x2−x and g(x)=−2x2−x, find (f−g)(x) and (f−g)(−2)
blondinia [14]

Answer:

(f - g)(x) = -8x²

(f - g)(2) = -32

General Formulas and Concepts:

<u>Algebra I</u>

  • Combining like terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -10x² - x

g(x0 = -2x² - x

(f - g)(x) is f(x) - g(x)

(f - g)(2) is f(2) - g(2)

<u>Step 2: Find (f - g)(x)</u>

  1. Substitute:                    (f - g)(x) = -10x² - x - (-2x² - x)
  2. Distribute -1:                 (f - g)(x) = -10x² - x + 2x² + x
  3. Combine like terms:    (f - g)(x) = -8x²

<u>Step 3: Evaluate</u>

  1. Substitute:                    (f - g)(2) = -8(-2)²
  2. Evaluate:                       (f - g)(2) = -8(4)
  3. Multiply:                        (f - g)(2) = -32

And we have our answers!

<h3>Answer:  96 dollars</h3>

===========================================================

Explanation:

Compute the area to get 12*8 = 96 square yards

We can think of it like having 96 squares and each square costs $1. So naturally the total cost is 96*1 = 96 dollars.
