Answer:
substitute x in y = 9/x
=> y = 9 or 1
So the number are 1 and 9 or 9 and 1
Answer:
m<2 is 17 degrees
Step-by-step explanation:
We can see that the angle at the vertex E was bisected to give two different but equal angles
Thus, we have it that;
2x + 7 = 4x-3
4x-2x = 7+ 3
2x = 10
x = 10/2
x = 5
so m<2 = 4(5) -3 = 20-3 = 17 degrees

Step-by-step explanation:
Using it's concept, it is found that the mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
<h3>What is the mean absolute deviation of a data-set?</h3>
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean is given by:
M = (65 + 58 + 64 + 61 + 67)/5 = 63.
Hence the mean absolute deviation is given by:
MAD = (|65-63| + |58-63| + |64-63| + |61-63| + |67-63|)/5 = 14/5 = 2.8.
The mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.

Answer:
The equation of the line is y = -1
Step-by-step explanation:
In order to find the equation,y = mx + c, you have to find the gradient first using the formula :
Let (x1,y1) = (-8,-1) & (x2,y2) = (-8,-1),
m = (-1)-(-1)/-8-(-8)
= 0
Now, we have found the gradient, next using the formula, y = mx + c to find the equation :
y = mx + c
Let m=0,
At (-8,-1)
-1 = 0(-8) + c
c = -1
y = -1
