Consider the suggested solution:
9 - answer D
10 - answer A.
Details are in the attachment.
The answers are:
P ' = (-4,-7)
Q ' = (-8,-7)
R ' = (-3,3)
------------------------------------------------------------------------------------
All you do is swap the x and y coordinates of the given points P, Q and R
The general rule is (x,y) ---> (y,x)
So that's why something like P = (-7,-4) becomes P ' = (-4,-7) when we reflect over the line y = x. The other points are handled the same way.
Answer:
5=1/3x-11
Step-by-step explanation:
Add eleven to each side to get 16=1/3x. Then multiply each side by three to get 48=x, so x=48.
Perimeter of square, 4a = 120
a = 30
diagonal = a√2 = 30√2 yards OR 42.3 yards
Answer:
this cannot be simplified is the best answer
Step-by-step explanation:
The answer i got is -(tan(x)+1)(tan(x)-1) / tan^2(x)
