Erik rode down an escalator, while raj rode up.
erik's elevation is represented by the equation h = 12 – 0.75t, and raj's elevation is represented by h = 0.75t. what does the point of intersection on the graph represent?

A. is the answer in this question

This law is sometimes called the grouping property. as you can see, regardless of how the numbers are grouped, the answer is still 13. the associative law of multiplication is similar to the same law for addition. it says that no matter how you group numbers you are multiplying together, you will get the same answer.

F(2) = 0f(-2) = 0due to the way the equation is, answers with 0 are correct.

Ican't solve. your equation is impossible. you can't have two equal signs.
