Answer:

x = -18

Step-by-step explanation:

Well you just have to do the this formula to find the slope

\frac{y2 - y1}{x2 - x1}  Plug in

\frac{5 - 12}{x - -4 } = \frac{-7}{?}=\frac{1}{2}

So we know x will have to be a negative to get 1/2

I would think x = -18 because -18 - -4 = -14 so it would look like this

\frac{5 - 12}{-18 - -4} = \frac{-7}{-14} =\frac{1}{2}

When you further simplify -7/-14 you get 1/2

Nataliya [291]

Answer:

10 seconds.

Step-by-step explanation:

The velocity at which they are approaching each other = 59 + 41 = 1000 km per second.

Velocity = distance  / time

So time =  distance / velocity

= 1000 / 100

= 10 seconds.

What is the m /___n <br> put only the number do not label your answer
Arisa [49]

Answer:

47

Step-by-step explanation:

m∠n = m∠p = 47

Since BD is parallel to AC, the alternating angles property applies.

Alternating angles are angles that are form in a Z pattern. The angles in the little rotated "v" formed in the top and bottom of the Z are equal.

Imagine a rotated Z forms from letters C to A to D to B.

Angles p and n are alternating angles, so they have the same measure.

Andre45 [30]

Answer:

1.d. None of these measures  (do not exist interpreted as all of these exist)

2.The mean is increased from 346.8 to 361.32

Step-by-step explanation:

After calculations we find that all the measures of central tendency exist for this data. The mean , median and mode can be easily calculated .

The mean is 346.8

The mode is 281

The median is 316

Suppose that the measurement 806 (the largest measurement in the data set) were replaced by 1169.  The mean would be affected by the change.

The mean is 361.32

The mode is 281

The median is 316

The mean is increased from 346.8 to 361.32

Which of the following is a solution of y - x &gt; -3<br><br> (6, 2)<br><br> (2, 6)<br><br> (2, -1)
frozen [14]
The correct point will make the inequality y-x>-3 "true."  Look at each of the 3 given points separately.  Subst. its coordinates into y-x>-3 and determine whether the resulting inequality is true or not.  Is 2-6>-3?  Is -4>-3?  No.  So, (6,2) is NOT a solution.  Continue by checking out the other two points in the same manner.
