Answer:
y = (x +7)/3
Step-by-step explanation:
Multiply the given equation by y/3:
.153
Or
153%
Hope this helps as
Orthocenter is the point of concurrence of the altitudes of the triangle.
This means Orthcenter is the point where the altitudes intersect.
Here one altitude is x = -1
The other altitude is y = x + 1
Substituting x = -1 in y = x + 1
We get
y = -1-1=0
Hence the point of intersection of the altitudes is (-1,0)
The orthocenter of the triangle whose altitudes are x = -1 & y = x+1 is (-1,0)
(-1,0) which is Option c) or the third option is the right answer.
DB should equal CB plus DC.
First write an expression to represent DC.
(x+168)-(3x+134)
x+168-3x-134
-2x+34
Then write an equal for DC plus CB equals DB
-2x+34+71= 153+2x
-2x+105= 153+2x
-4x+105=153
-4x=48
x= -12
Now plug in the value of x to find DB
153+2(-12)
153-24
129
Final answer: 129
