zlopas [31]

Answer:

<u>Given</u>:

  • R(x) = 59x - 0.3x²
  • C(x) = 3x + 14

<u>Find the following</u>:

  • P(x) = R(x) - C(x) = 59x - 0.3x² - 3x - 14 = -0.3x² + 56x - 14
  • R(80) = 59(80) - 0.3(80²) = 2800
  • C(80) = 3(80) + 14 = 254
  • P(80) = 2800 - 254 = 2546

What is the slope of the line on the graph?
erma4kov [3.2K]

Answer:

m=\frac{1}{2}

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step 1: Find 2 points

(0, 2) y-int

(-4, 0) x-int

Step 2: Plug into slope formula to find slope <em>m</em>

<em />m=\frac{2-0}{0-(-4)}<em />

<em />m=\frac{2}{0+4}<em />

<em />m=\frac{2}{4}<em />

<em />m=\frac{1}{2}<em />
