4 − –5f = –66 f = _______
Paraphin [41]

Answer:

f = -14

Step-by-step explanation:

given:

4 − (–5f) = –66

4 + 5f = -66   ( subtract 4 from both sides)

5f = -66 - 4

5f = -70  (divide both sides by 5)

f = (-70) / 5

f = -14

What is the slope of the following graph? (write your answer as a fraction unless divided by 1. Do not use spaces in your answer
alexira [117]

The slope of the graph is 4/5

<h3>How to determine the slope</h3>

Using the formula

Slope = Δ y-axis / Δ x- axis

y2 = -4

y1 = 0

x2 = -5

x1 = 0

Slope = \frac{y2 - y1}{x2 - x1}

Substitute the values into the formula

<em>Slope = </em>\frac{-4 - 0}{- 5 - 0}

Slope = \frac{-4}{-5}

Slope = \frac{4}{5}

Therefore, the slope of the graph is 4/5
