16<ac<24
If it is less than 16 it will not form a triangle and if it is more than 24 the other two legs will not be larger than ac is.

Which ordered pairs is a solution to -5x + 3y &gt; 12?
GaryK [48]

9514 1404 393

Answer:

  (-5, 5), (2, 8), (-6, 0)

Step-by-step explanation:

It is convenient to graph the solution, then plot the points to see which fall in the solution area.

The point (3, 9) falls on the boundary line, which is <em>not</em> part of the solution set.

The points that are solutions are ...

  B(-5, 5)

  E(2, 8)

  F(-6, 0)

The lines are parallel. Find the slope-intercept form of the equation y₂.
Bas_tet [7]
Since the lines are parallel and you know the slope of y_{1} is -2, you know the slope of line y_{2} will also be -2. You can see on the coordinate grid that line y_{2} crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get y_{2} = -2x - 1.

Please anybody help me in this
Simora [160]

Answer:

<h2>a) 0.38</h2><h2>b) 0.62</h2><h2>c) 0.78</h2><h2>d) 0.03</h2><h2>e) 0.02</h2><h2>f) 0.62</h2><h2>g) 0.38</h2>

Step-by-step explanation:

a)

Probability of a owner to be moved = \frac{total owner}{total Americans} = \frac{14.8}{39} = 0.379 ≅ 0.38

b)

Probability of a renter to be moved = \frac{total renters}{total Americans} = \frac{24.2}{39} = 0.62

c)

Probability of a person who moved in the same state = \frac{Persons who moved to the same state}{Total Americans} = \frac{30.4}{39} = 0.779 ≅ 0.78

d)

Probability of a person who moved to a different country = \frac{Total moved to different country}{Total Americans} = \frac{1.3}{39} = 0.033 ≅0.03

e)

Probability of a owner who moved to a different country = \frac{Owners that moved to different country}{Total people who moved to different country} = \frac{0.3}{14.8} = 0.02

f)

Probability of a renter moving in the same state = \frac{Renter that moved in the same state}{Total persons moved in the same state} = \frac{18.7}{30.4} = 0.615 ≅ 0.62

g)

Probability of an owner moved to different state = \frac{Owners moved in different state}{Total moved in different state} = \frac{2.8}{7.3} ≅0.38

What is the distance between the points (-2,4) and (6,-4), rounded to the nearest tenth
jarptica [38.1K]

9514 1404 393

Answer:

  11.3 units

Step-by-step explanation:

The distance can be found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((6 -(-2))² +(-4-4)²) = √(8² +(-8)²) = √(64·2)

  d = 8√2 ≈ 11.3

The distance is approximately 11.3 units.
