Answer:
A system of equations is a set of equations which are collectively satisfied by one solution of the variables.
Answer:
(4,-2)
Step-by-step explanation:
If we are reflecting a point across the y-axis, that point must be on the same horizontal line that the pre-mage is was, this means the y coordinate must remain the same. Now we want the points on both sides of the y-axis to have the same distance. x and -x have the same distance from 0. This means you will need to take the opposite of x.
So a point (x,y) being reflected over the y-axis will give (-x,y).
( x , y)->(-x,y) means we have:
(-4,-2 )->(4,-2)
You can graph this to confirm it looks like a reflection through the y-axis.
If there is suppose to be a negative sign.
3x -1(2x + 4x - 6)
Distribute the -1 to all terms within the parenthesis
-1(2x + 4x - 6) = -2x - 4x + 6
3x - 2x - 4x + 6
Simplify. Combine like terms
(3x - 2x - 4x) + 6
-3x + 6
-3x + 6 is your answer
hope this helps
Question, do you need the angles? If it’s the angles use a protractor and measure.
So the 8/30 would be juniors so the percentage would be 26%
