I got C. 20 square units.
I could be wrong, but probably not. It was hard to figure out what the plot numbers were and the answer choices because the picture was super blurry. That's why I said I might be wrong.
Hope this helps!! :-)
Answer:
y=1/2x-4
Step-by-step explanation:
2y-x=-8
2y=x-8
y=1/2x-4
The solutions of x and y?
2x+y=8...(1)
x-2y=-1...(2)
for (2), x=-1+2y...(3)
sub(3) into(1),
2(-1+2y) +y=8
-2+4y+y=8
5y=10
y=2
sub y=2 into(3)
x=-1+2(2) =3
therefore, x=3,y=2
Answer:
155°
Step-by-step explanation:
z = 65° + y
y is a right angle
=> y = 90°
=> z = 65° + 90° = 155°
Log(1) is equal to 0 because 10^0 is 1
