1. Distribute
5(2n-4)
10n-20
9(n+2)
9n+18
10n-20=9n+18
2. Combine like terms
combine the terms with “n”, and then combine the other numbers.
Hope this helps!
A few ways. you can enter it into a calculator for one, but the easiest way would be to reference a unit circle and look for an ordered pair where sin (the y value), is equal to -1/2
on a unit circle, the sin value is -1/2 at 7pi/6 and 11pi/6
because sin is the y value, it will additionally be in the quadrants III or IV based on the fact that (-1/2) as a sin value IS a negative and would have to be found in a quadrant in which sin is negative (the lower half of a coordinate plane, in this case)
Answer:
Its either A or D because its reflection so that cancels out B and C
im not sure if this helps u or not but at lest it cancels out 2 of the options
The reflection of a horizontal line has the same result as a rotation of 90 degrees clockwise.
Step-by-step explanation:
When an image is rotated 90 degrees counterclockwise the shape is still congruent but in a different quadrant. The same is true when an image is reflected across a horizontal line.
Pay attention in math class! in higher grade levels, this is gonna show up EVERYDAY! no joke
In these types of problems, you need to use PEMDAS also.
((4)+3)+(13(-2)-5)
(7)+(-31)
7-31
-24
<u><em>C</em></u>
