Answer:
the substitution method is one way to solve linear equation. the substitution method is when substitute the one y value with the other:
example :
x+y=10
y=10-x ( value of y)
2x+y=12 ( substitute the value of y in the equation )
2x+(10-x)=12
2x+10-x=12 ( now solve for x)
x=12-10
x=2 ( substitute the value of x in the equation x+y=10)
x+y=10
2+y=10
y=10-2
y=8

Answer:
Step-by-step explanation:
.72x+3=0.3(2.4+15)
.72x+3=0.72+4.5=0.72+4.50
.72 x=5.22
Answer:
6v+1
Step-by-step explanation:
The answer is Angle Bisector.
I think this because if it were to be perpendicular the triangle would have to be congruent in SSS theorem or other.
I hope this helps!
