Answer:

(f - g)(x) = -x² + 3x + 5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Function Notation
  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x + 5

g(x) = x²

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

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

  1. Substitute:                   (f - g)(x) = 3x + 5 - x²
  2. Rewrite:                       (f - g)(x) = -x² + 3x + 5

Hoochie [10]

Answer:

B. 5√3 is your answer.

Step-by-step explanation:

This is an equilateral triangle, which means that all external sides (that make up the triangle) have the same measurement.

This means that line segment AC = 10.

Solve for the measurement of line segment AB. Line Segment AB is 1/2 of AC, making it: 10/2 = 5

Line AB = 5

Line AD = 10

This is a 1, √3, 2 triangle, in which:

1 = 5

2 = 10

Solve for √3. Multiply √3 with the 1:

5 x √3 = 5√3

B. 5√3 is your answer.

Let the number of large bookcases be x and number of small bookcases be y, then
Maximise P = 80x + 50y;
subkect to:
6x + 2y ≤ 24
x, y ≥ 2

The corner points are (2, 2), (2, 6), (3.333, 2)
For (2, 2): P = 80(2) + 50(2) = 160 + 100 = 260
For (2, 6): P = 80(2) + 50(6) = 160 + 300 = 460
For (3.333, 2): P = 80(3.333) + 50(2) = 266.67 + 100 = 366.67

Therefore, for maximum profit, he should produce 2 large bookcases and 6 small bookcases.
