Answer:

Step-by-step explanation:
Given:



(segment addition postulate)
(substitution)
(subtracting 17 from each side)

(Subtracting 5y from both sides)


(dividing both sides by -2)

Plug in the value of y


6yd
8yd a =48sq yd (6×8=48)
4yd
12yd a=48sq yd (4×12=48)
Answer:
C) Ken added 19 to both sides of the equation rather than subtracting 19.
Step-by-step explanation:
I Just Took The Test On Edge
Y = -1x+b
replace x and y to find b
2 = -1*2+ b
b = 4
Final:
y = -1x + 4
