Answer:
True
Step-by-step explanation:
There are an odd number of negative signs (3)
If there is an odd number it is negative, but if it is even then the result will be positive
Here's a deeper explanation
-1 times -1 is simply 1
Then 1 times -1 is -1
Our final answer is -1 so this is true.

Answer: Choice C, Ro, 270 </h3>
270 degree counterclockwise rotation around the origin
=============================================================
Check out the diagram below. In the diagram, I only focus on points A and A'.
We have A = (-3,4) move to A ' = (4, 3). We see the x and y coordinates swap places. Then the new second coordinate -3 becomes positive, or it has flipped sign. So the rule applied here is which describes a 90 degree clockwise rotation; which is equivalent to a 270 degree counterclockwise rotation
The other points follow the same idea.
F(x) = -5x + 3
f(-4) = -5(-4) + 3
f(-4) = 20 + 3
f(-4) = 23
Answer:
46 and 59
Step-by-step explanation:
let the smaller number be n then the larger number is n + 13 and summing them gives the equation
n + n + 13 = 105
2n + 13 = 105 ( subtract 13 from both sides of the equation )
2n = 92 ( divide both sides by 2 )
n = 46
the 2 numbers are n = 46 and n + 13 = 46 + 13 = 59
