Answer:
- 18.6
Step-by-step explanation:
Let's say that the unknown value here is c. Although we are given two points on the line, it is only necessary to use one as there is only one unknown value, so let's say we choose the point (6, -12) and substitute this into the equation:
-12 = 1(6) - c
-12 - 6 = -c
-18 = -c
c = 18
Thus the equation for the line is y = 1x - 18
Answer:
The mean of these statistic is 2.18.
Step-by-step explanation:
According to the chart, from 1986-1996, unintentional drug overdose deaths per 100,000 population began to rise.
The given data set is
2, 1, 2, 2, 1, 2, 2, 3, 3, 3, 3
Formula for mean:
Using this formula, the mean of the data is
Therefore the mean of these statistic is 2.18.
Answer:
The segment bisector is MN
Step-by-step explanation:
MN divides XY into two equal lengths
The equivalent system of equations that would guarantee a solution of (3,-1) are
- a. (p+f)x+(q+g)y= r+h and fx+gy=h
- d. px+qy=r and (f-2p)x+(g-2q)y=h-2r
- e. px+qy+r and 5fx+ 5gy = 5h
<h3>How to determine the system of equations?</h3>
The system of equations is given as:
px +qy =r
fx + gy = h
Add both equations
(p + f)x + (q + g)y = r + h
Multiply the second equation by a constant (say 5)
5fx + 5gy = 5h
Multiply the first equation by a constant (say 2)
2px + 2qy = 2r
The combination of any of the above equations to the given equation would guarantee a solution of (3,-1)
Hence, the equivalent system of equations are (a), (d) and (e)
