Help PLease! PLease explainn how to do these types of equations!
leonid [27]

Answer:

4xy See image.

Step-by-step explanation:

Remember for division questions to use Keep, Change, Flip. You will Keep the first term the same. Change the divide to times. And Flip the second term (turn it upside down, in math this is called the reciprocal)

Also, you need to know when you you get to the part where everything is times, then you times: top×top, and bottom×bottom.

Once everything is times, you can rearrange the order and cancel (cancel is not really the mathy thing happening, you are dividing---

x/x is 1 and y/y is 1,

10/5 is 2, 6/3 is 2) See image.

Which of the following describes the translation of the graph of y = x2 to obtain the graph of y = -x2 - 3?
Ray Of Light [21]

Answer:

reflections across the x axis and a shift down 3 units

Step-by-step explanation:

y = x^2

The negative sign means  it is a reflection across the x axis y = −f(x)

y = -x^2

The subtraction of 3 means we are shifting down 3 units

y = -x^2 -3
