The point (-3,-2) is rotated 180 degrees about the origin. what are the coordinates of its image?

den301095 [7]

Answer:

The coordinates of the image are (3,2)

Step-by-step explanation:

we know that

The coordinates of the pre-image are (-3,-2)

This point is located on III Quadrant

If the point is rotated 180 degrees about the origin

then

The image will be located on I Quadrant

The rule of the rotation is equal to

(x,y) ------> (-x,-y)

(-3,-2) -------> (3,2)

Factorise the following.

Alika [10]

Answer:

x⁴ - y⁴= (x²)²- (y²)² = (x² + y²)(x²- y²) = (x²+y²)(x)²-(y)²=(x²+y²)(x+y)(x-y)

49x²-16/25= (7x)²- (4/5)²=(7x+4/5)(7x-4/5)

Travis is deciding how to study math tonight he is choosing between studying ofG patterns P or equations E he also is deciding w

expeople1 [14]

Answer:

GT, GV, PT, PV, ET, and EV.

Step-by-step explanation:

Given that

The number of topics Travis has to chose from are 3 topics(G, P, E).

The number of ways Travis can study each topic are 2 ways(T, V).

Essentially, the number of combinations Travis is expected to be able to chose from is given as

The number of combinations = The number of topics * The number of ways

The number of combinations = 3 * 2

The number of combinations = 6

Therefore, the total possible combinations has to be

GT, GV, PT, PV, ET, and EV

Explain how you could use the interactive table to tell if

Tasya [4]

Answer:

Tables are essentially the source for all the charts. They are best used for comparison, composition, or relationship analysis when there are only few variables and data points. It would not make much sense to create a chart if the data can be easily interpreted from the table.

The tables help us to compare the values of those two sets of the data that have been presented in different ways.
