A perpendicular bisector
this means the length IJ=JK and the angles IJB, BJK are 90° (and their congruent angles too)
but this does not mean AB=IK, because their lengths can be arbitrary
for a similar reason AJ=IJ is wrong, essentially the same statement but with half lengths
BI=BK is true, because it is a bisector of IK this means the sides IJ=JK and JB is a shared side, therefore also having the same length. We also know IJB and BJK are congruent angles, so all in all these are congruent triangle and therefore also share the side length
BI=AK is false, because we don't know where the intersection point j is on AB, it could split the length into any arbitrary ratio, in case these are two equal sides then it would be true, but it doesn't hold for all other possibilities
so BI=BK is the solution
-4(v+1)
mutiply the bracket by -4
-negative sign and +positive sign= -negative sign
(-4)(v)= -4v
(-4)(1)= -4
Answer:
-4v-4
LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL
Answer:
The triangle is not equilateral.
Step-by-step explanation:
Distance formula:
Distance from (a, a) to (-a, -a):
Distance from (-a, -a) to (-3a, 3a):
Distance from (-3a, 3a) to (a, a):
The three sides do not have the same length, so the triangle is not equilateral.
Answer:
2.4 or 12/5
Step-by-step explanation:
The slope formula is (y2-y1) divided by (x2-x1).
First, you label each number by their x and y.
-4 will be axis x 1
2 will be axis y 1
-9 will be axis x 2
-10 will be axis y 2.
Then substitute the variable into the formula.
(-10 subtract 2) divided by (-9-(-4)).
Next, solve. Once you solve you will get -12/-5 = 2.4
Finally, simplify the answer. if it is already simplify, that will be the answer.
