The mean
is
(the sum of the values of all the points)
divided by
(the
number of points).
There are 10 points on the graph.
Their 'A' values add up to 50.
The mean of the 'A' values is (50/10) = 5 .

the Since D is the midpoint of AC, we can say that AD=DC, then the triangles ADE and CDF would be similar by the SAS theorem which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
If the triangles are congruent, their angles are equal.
Answer:
4x+3y-10=0
Step-by-step explanation:
first find the gradient of the line that is perpendicular to the line of interest.
y2-y1/x2-x1
3--3/6--6
=3+3/6+6
=9/12
3/4
The gradient of the line of interest is the negative reciprocal of 3/4. Therefore m is -4/3
next, substitute information into
y-y1=m(x-x1)
y-2=-4/3 (x-1)
multiply both sides of equation by 3
3y-6=-4 (x-1)
expand brackets
3y-6=-4x+4
rearrange in general form
4x+3y-10=0
I’m sorry I don’t what this is you just said if m so I’m just gonna help you out and say d because I don’t kno what you are talking about
