Answer:
(2,-2)
Step-by-step explanation:
The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.
-3x+4 = 4x-10
-3x-4x+4-4 = 4x-4x-10-4
-7x = -14
-7x/-7 = -14/-7
x = 2
Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.
y = 4(2)-10
y = 8-10
y = -2
Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)
Answer:
Step-by-step explanation:
By the definition of an angle bisector, we have that 
.
We can add 
to both sides to get 
.
We can then subtract 
from both sides to get 
.
We can finally divide both sides by 
to get 
Answer:
Step-by-step explanation:
a=1
r=-6/1=-6
Answer:
In my opinion both of the lines are tangent.
Step-by-step explanation:
Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.
Answer:
Not proportional
Step-by-step explanation:
If x and y are proportional then the equation relating them is
y = kx ← k is the constant of proportionality
To determine if x and y are in proportion then k must be equal for all ordered pairs, that is
k = 
(2, 0) k = 
= 0
(4, 2) → k = 
= 
(6, 4) → k = 
= 
(8, 6) → k = 
= 
Since k is not constant for all values then not in proportion
