Answer:
Step-by-step explanation:
Each string makes a shortest distance from the vertices to opposite sides.
This is the altitude.
Altitudes are concurrent in a point that is known as the orthocenter.
This has got to be THE dumbest question bro
Answer:
v = 6/7 + 2/7y
Step-by-step explanation:
<u>Step 1: Distribute</u>
-7(-2v + 5) - 4y = 2(1 - 9) - 7
14v - 35 - 4y = 2 - 18 - 7
Step 2: Add 35 to both sides
14v - 35 + 35 - 4y = -23 + 35 + 4y
14v = 12 + 4y
Step 3: Divide both sides by 10
14v / 14 = 12 + 4y / 14
v = 6/7 + 2/7y
Answer: v = 6/7 + 2/7y
Answer:
(-2,-1,-3)
Step-by-step explanation:
5x-4y-3z=3
x+y-z=0
x=3y+1
Multiply the second equation by -3
-3(x+y-z)=0*3
-3x-3y+3z =0
Add this to the first equation to eliminate z
5x-4y-3z=3
-3x-3y+3z =0
--------------------
2x-7y =3
Substitute x =3y+1 into the above equation
2(3y+1) -7y=3
Distribute the 2
6y +2 -7y = 3
Combine like terms
-y+2 =3
Subtract 2 from each side
-y+2-2 = 3-2
-y = 1
Multiply by -1
-y*-1 = 1*-1
y =-1
We need to find x
x=3y+1
x =3(-1) +1
x =-3+1
x= -2
Now we need to find z
x+y-z=0
-2+-1-z=0
-3-z=0
Add z to each side
-3-z+z=0+z
-3=z
x=-2, y=-1 z=-3
(-2,-1,-3)
