Answer:
See below.
Step-by-step explanation:
The Slope of PQ is (v - z) / (w - x).
The slope of P'Q' =
(v + b) - (z + b)
--------------------- = (v - z) / (w - x)
(w + a - (x + a)
Both lines have a slope that is (v - z)/ (w - x).
So both lines are parallel.
Answer:
19) ( 
)^2 = 
20) -
= -81
21) 
= 16
Step-by-step explanation:
The only wrong ones are
19) ( )^2 =
20) - = -81 ... negative is not inside a parenthesis that's why it is still negative
21) you can add another way is = 16
Everything else looks good. Great job!
Ok, first let's multiply:
3 x 1/6 = 3/6 (simplify:) 1/2
Then multiply again:
3 x 1/9 = 3/9 (simplify:) 1/3
Now the expression is simplified to (1/2x, 1/2y)
Hope this helped! Please comment or DM me if you have anymore questions or don't understand :)
