When (-5, 2) is reflected across the y-axis then it becomes (5, 2). When (-5, 2) is reflected across the x-axis, it becomes (-5, -2)
I hope this helps out!
you put it over 1 and divide it by 10
Start with the bottom surface area, 7x7=49
then go to the triangles, base times height divided by 2, so (7x14)/2=49
and since there are 4 triangles, multiply 49 by 4 = 196 and add the area of the bottom, which all adds up to 245
12-(x+3)=10
Simplify the equation.
12-x-3=10
Combine like terms.
(12-3)-x=10
Simplify.
9-x=10
Subtract 9 from both sides to get x by itself.
-x=1
Divide both sides by -1 to get x by itself.
x=-1

Column Resolution
Rs = 2[(tr)y - (tr)x]/[Wx + Wy]
= 2[17.63 - 16.4]/ [1.11 + 1.21] = 1.06
Average no. of plates in the column for substance x
N = 16(tr/ W)^2
N = 16(16.4/1.11)^2
N = 3490 plates
Average no. of plates in the column for substance y
N = 16(tr/ W)^2
N = 16(17.63/1.21)^2
N = 3397 plates
Plates Height
H = L/N
For substance x
H = 30/3490
H= 0.00916905 cm/plate
For substance y
H = 30/3397
H = 0.00883132 cm/plate
