Answer:
x = -8
Step-by-step explanation:
y = 3x/4
Substitute the value of -6 into y.
-6 = 3x/4
Multiply both sides by 4.
-24 = 3x
Divide both sides by 3.
x = -8.
Answer:
30
Step-by-step explanation:
Pythagorean theorem states that a^2 + b^2 = c^2
this theorem only works on triangles with an angle of 90 degrees or a right triangle.
18^2 + 24^2 = 900
the square root of 900 is 30
I did the square root of 900 because the square root is the 'opposite' of squaring which is what you need to do in order to find 'c' is the Pythagorean theorem. 'a' is 18, and 'b' is 24
Answer is 30
Answer:
Step-by-step explanation:
Given : Vertices of Triangle 
, 
and 
To find : Centroid of a triangle
The centroid of a triangle is the point of intersection of the three medians of the triangle.
The formula to calculate the centroid of a triangle is:
Where, 
are the coordinates of the centroid
Substituting the values in the formula gives us:
Therefore,
Answer: 75
Step-by-step explanation:
Multiple all those numbers together and then divide by 3
Answer: x+y+1=0
Step-by-step explanation:
m=y2-y1/x2-x1
= 4-(-2) /-5-1
=6/-6
=-1
equation of line
y-y1=m(x-x1)
y-(-2) =-1(x-1)
y+2=-x+1
x-1+y+2=0
x+y+11=0
