18x^2 - 32 =
2(9x^2 - 16) =
2(3x + 4)(3x - 4) <==
answer is 4
Answer:
Reference angles are always acute.
We can find the reference angle with the "formula"
π
−
θ
, where
θ
is our given angle.
We can plug

Answer:
HERE IS YOUR ANSWER
Step-by-step explanation:
4
The figure is being reflected over the x axis (horizontal axis). Any y coordinate that is negative becomes positive, and vice versa. The x coordinate stays the same.
If we have some point (x,y) as the original point, then it would turn into (x,-y). Note how the y coordinate has a negative on it now.
So we can say

which is what choice C is saying.
Choice C is the answerChoice D is NOT the answer because the words "y axis" under the 'r' should be "x axis" instead.
