Answer:

177 and 178

Step-by-step explanation:

First, the expression for the 2nd mile marker is x+1.

Now, you add x and x + 1 together to get 2x + 1

Next, make 2x + 1 equal to 355

Now subtract 1 and then divide by two on both sides to get x = 177.

This means that the first mile marker is 177 and the next is 178.

Which graph represents 9x2 – 16y2 – 54x + 64y – 127 = 0?

klasskru [66]

Answer:

Right now I'm wondering what kind of class you are taking to get such a weird graph, but I graphed it for you on the screenie.

Step-by-step explanation:

You should though recheck your question for exponents, as 9x2 could be interpreted differently.

Since exponents to not transition well here, I can assume that it was a 9x^2, so please add an exponent symbol ^ between the variables and exponents next time.
