Answer:

  see attached

Step-by-step explanation:

We cannot really do the construction for you, but we can tell you how it needs to go. The three sides of the triangle will have a length in cm that is equal to the given length in km divided by 20.

  AB = 6 cm

  BC = 8 cm

  AC = 9 cm

__

The area each station can be heard will be a circle of radius (100 km)/(20 km) cm = 5 cm. The overlap of those circles is the area you are to shade.

The attached diagram should give you the general idea. (Scale units are cm.)

_____

<em>Additional comment</em>

It works well to find B as the intersection of arcs of radius 6 cm and 8 cm, drawn from centers A and C, respectively.

What is the equation of the line in slope intercept form using these points?
deff fn [24]

Answer:

y = -x - 1

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. To find the slope given two points, we can use the formula \frac{y_2-y_1}{x_2-x_1} and plug in the corresponding variable.

  • \frac{5-(-2)}{-6-1}
  • \frac{5+2}{-7}
  • \frac{7}{-7}
  • -1

3. Okay, so the slope is -1x or just -x. This means that the equation looks like this so far: y = -x + b

4. To find b, the y-intercept, we can take the equation of b = y_1 - m * x_1 and plug in the values!

  • b = -2-(-1)*1
  • b = -2 + 1 * 1
  • b = -1 * 1
  • b = -1

5. Now that we have our y-intercept and slope, let's plug in those values and find the equation!

  • y = -x - 1

Therefore, the equation of the line is y = -x - 1. I hope this helped you!

Write 18z − 7 (−3 + 2z) in simplest form. Select True or False for each statement.
vfiekz [6]

Answer:

Simplest form = 4<em>z </em>+ 21

Case 1: True, Case II: false and Case III: true

Step-by-step explanation:

18<em>z </em>- 7( -3 + 2z)

= 18<em>z</em> + 21 - 14z

= 18<em>z</em> -14z + 21

= 4<em>z </em>+ 21

So, in the above expression we have two terms. First term is 4z and second term is 21.

So the first case is true. As the expression has two terms.

The coefficient of <em>z </em>is a number which is multiplied by <em>z</em>. Therefore, Second case is false as the coefficient of <em>z</em> is 4.

The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.
