Wassup wit it g, I’m on here tryna cheat too but might as well help a homie out while I’m at it, your answer finna be 40
Answer:
x=7
y= -2
Step-by-step explanation:
x+3y=1 ---------------- (1)
−3x−3y=−15 -------------(2)
Solve Equation (1) for x
x=1−3y
Substitute x=1−3y in equation (2)
−3(1−3y)−3y=−15
−3+9y−3y=−15
−3+6y=−15
6y=−15+3=−12
y=−12/6=−2
y=−2
Substitute y=−2 in equation (1)
x+3(−2)=1
x−6=1
x=1+6=7
x=7
Hello from MrBillDoesMath
Answer:
See below
Discussion:
Note the Question incorrectly shows (2n^2 +1) ^ 2. It should be (2n + 1) ^2.
So
(2 n + 1) ^2 - (2n +1) =
4n^2 + 4n + 1 - 2n - 1 = ( -1 + 1 = 0)
4n^2 + 4n -2n + (1-1) =
4(X) = 2 (2X)
Key point. The end result of the evaluation is a multiple of 2 so the result is an even integer.
Thank you,

I think your teacher may have made a typo. Refer to the diagram below. If we ignore segment ZA for now, we can see a rectangle forms with angle W = angle Y = 90. Also, we can see that WX = 6 is the horizontal base and WZ = 8 is the vertical height.
However, the side opposite WZ (which is XY) should also be 8 cm tall, and not 6 cm. If XY was 6 cm, then point Y would move to where point A is located (and the quadrilateral would be WXAZ instead of WXYZ). This new quadrilateral would not have a 90 degree angle at point Y's new location.
In other words, if we want angle Y to be 90 degrees, then side XY must be 8 units long. I have a feeling this is where the typo is, but your teacher might have been intending to say something else.
