Your answer is D. All of these statements are true.
The answer is 51 first u multiply and divide then calculate
6 x 6 x 6 x 6 x 6 x 6 x 6 x 6
To get 10% of 40, you move the decimal point one way to the left. So 10% of 40 is 4
Now you need 2% and because you know 10% is 4, you divide that by 10 and multiply it by 2 because of the 2%
4/10=.4 .4•2=.8
Now you add them
4+.8=4.8
12% of 40 is 4.8
Set the argument -1/2x equal to the x coordinate of the given point 6. Solve for x
-1/2x = 6
x = 6(-2)
x = -12
So x = -12 makes the equation -1/2x = 6 true.
If we plug x = -12 into f(-1/2x) we get f(6)
Since we know that (6,-8) is on the graph of f(x), we know that (-12,-8) is on the graph of f(-1/2x)
What happens is that there's a reflection over the y axis (due to the minus sign in -1/2x) and there's a horizontal stretch by a factor of 2. So the graph of f(-1/2x) appears to be wider than f(x).
In summary, the final answer is (-12,-8)
