The ratio of a 45-45-90 triangle is x-x-xrad2
So we can make the equation 44=xrad2
we can see that the answer is 22rad2 so the answer is b
11.35-6:35= 5 hours
5 x 4 = 20 this is how many degrees it rose in 5 hours
-18+20 = 2 degrees
d is your answer
In looking at it I would guess it is asking which of the points is on the line? To answer that you would have to take each point an plug it into the equation and see if it is true.
3x - 7 = y
A(9,20)
3(9) - 7 = 20
27 - 7 = 20
20 = 20 True - this point is on the line
B(5,0)
3(5) - 7 = 0
15 - 7 = 0
8 = 0 False - this point is not on the line
C(3,2)
3(3) - 7 = 2
9 - 7 = 2
2 = 2 True - this point is on the line
I hope this helps
Well, you have to ask the question first.
