To rotate a figure
90 degrees(-y,x)
180 degrees(-x,-y)
270 degrees(y,-x)
If your original point is (1,2) or example and you want to rotate it say 270 degrees the final point would be (2,-1)
Hope this helped!!!!!

Which graph represents an odd function?<br><br>Answer by using: A, B, C, or D for each graph.
vladimir1956 [14]

Answer: The correct option is C.

Explanation:

A function is called an odd function if,

f(-x)=-f(x)

It means if the points are in the form of (x,y) then (-x,-y) is also in the graph.

Reason for correct option:

In option C, a point  (1,2),

It means,

f(1)=2

And we have another point (-1,-2).

f(-1)=-f(1)=-2

The other points are (2,3),(-2,-3),(3,-1),(-3,1),(4,0),(-4,0). Therefore the function is an odd function.

Reason for incorrect option:

In option A, a point is (1,3), therefore the value of function at x = -1 should be -3.

But the value of function is 1 at x=-1, therefore it is not an odd function.

In option B, a point is  (1,0), therefore the value of function at x = -1 should be 0.

But the value of function is -3 at x=-1, therefore it is not an odd function.

In option D, a point is (1,-1), therefore the value of function at x = -1 should be 1.

But the value of function is -1 at x=-1, therefore it is not an odd function.

Please help me with my algebra homework (Attachment)
Lapatulllka [165]

Answer:

D.

Step-by-step explanation:

To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.

What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5

B.

left = -5 - 5 = -10

right = -(2/3)(4 + 4) = -16/3

So it's D. Let's verify:

D.

left = -5 + 5 = 0

right = -(2/3)(4 - 4) = 0

Checks out.
