Answer:
D. "If the graph of two variables is not a linear function, then the two variables are not directly proportional"
Step-by-step explanation:
The contrapositive of a statement is basically you changing the conditional part of the statement with its result and then finding the negative of both. This is called Contraposition.
So, for the statement given:
"If two variables are directly proportional, then their graph is a linear function."
The contrapositive will be:
"If the graph of two variables is not a linear function, then the two variables are not directly proportional"
I am currently taking Geometry right now, so I understand where you are coming from. I think it's just a matter of approaching it differently. My teacher always says she is trying to get us to think, not memorize. If you think a tutor would help you, then go for it! Just make sure you are learning the material not just for the grade, but so that you actually understand it. That's the most important part. Good luck!
Answer:
The explanation is given below with the diagram.
Step-by-step explanation:
Given:
Δ ABC is an Isosceles triangle with base AB.
D is the midpoint of AB
∴ AD = BD
To Prove:
Proof:
Isosceles triangle property:
If Δ ABC is an Isosceles triangle with base AB, then the two sides are congruent and the base angles are congruent.
