Answer:

Step-by-step explanation:

1. 10² + 7² = x²

149 = x²

x = √149

2. x² + 19² = 21²

x² = 21² - 19² = 80

x = √80 = 4√5

3. x² + 16² = 27²

x² = 27² - 16² = 473

x = √473

4. 5.3² + 12.8² = x²

191.93 = x²

x = √191.93

5. 9² + 20² = x²

481 = x²

x = √481

6. 31 = x + 2√(19²-17²) = x + 2·6√2 = x + 12√2

x = 31 - 12√2

What is the slope of the line passing through the points (−3, 4) and (4, −1)?

Igoryamba

Note:
The slope of a straight line passing through the points (x₁, y₁) and (x₂, y₂) is
$m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

The two given points are (-3,4) and (4,-1). Therefore the slope is
$m= \frac{-1-4}{4-(-3)} = \frac{-5}{7}$

Answer: $- \frac{5}{7}$
