Which statement explains how you could use coordinate geometry to prove the diagonals of a quadrilateral are perpendicular?
2 answers:
Answer:
(B)Use the slope formula to prove the slopes of the diagonals are opposite reciprocals.
Step-by-step explanation:
Two lines are perpendicular if the product of their slope is -1. That is, the slope of one is the opposite reciprocal of the other.
Mathematically, if their slopes are
<u>Therefore, the correct option is B.</u>

Geometric sequences go up due to a common ratio. Here the common ratio can be worked out by dividing a term by its previous term e.g term 2 divided by term 1.
Therefore the common ratio is 6.
Therefore the common ratio is 6.
Answer:
<h3>⇒ A. 2 should be distributed as 2y + 12, y = 6</h3>Step-by-step explanation:
Here are the steps to solve this equation:
<u>Given:</u>
First step: 2(y+6)-4y
Use the distributive property.
<u>Distributive property:</u>
<h3>⇒ A(B+C)=AB+AC</h3>2(y+6)
2*y=2y
2*6=12
2y+12
Isolate the term of y from one side of the equations.
2y+12=4y
Subtract by 12 from both sides.
2y+12-12=4y-12
Solve.
2y=4y-12
Then, you subtract by 4y from both sides.
2y-4y=4y-12-4y
Solve.
2y-4y=-2y
-2y=-12
Divide by -2 from both sides.
Solve.
Divide the numbers from left to right.
<u>Solutions:</u>
-12/-2=6
- <u>Therefore, the correct answer is A. "2 should be distributed as 2y+12, y=6".</u>
