The centroid is found by intersecting the medians of a triangle
Answer: Choice B
This is something to memorize or have on a reference sheet
Side notes:
1) The altitudes cross to form the orthocenter
2) The perpendicular bisectors intersect at the circumcenter
3) The angle bisectors intersect at the incenter
Answer:
x=11/2
Step-by-step explanation:
4+5x‒7=10+3x‒2
5x‒3=8+3x
5x‒3x=8+3
2x=11
2x/2=11/2
x=11/2
Answer:
(5, - 2)
Step-by-step explanation:
2x+y>3
x-y>1
2x + y > 3 - - - - (1)
x - y > 1 - - - (2)
Using trial and error method :
Using :
(5,-2)
2x + y > 3
2(5) + (-2) > 3
10 - 2 > 3
8 > 3 (true)
x - y > 1
5 - (-2) >1
5 + 2 > 1
7 > 1 (True)
For 0,5
2x + y > 3
2(0) + (5) > 3
0 + 5 > 3
5 > 3 (true)
x - y > 1
0 - (5) >1
-5 > 1
--5 > 1 (false)
Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)
