7 because I know and it’s right
I guess just work backwards.
x=-3
2x=-6
x=-x-6
There ya go :P
I think it could be B because it is not a 90 and it too small for an 82 but too big for a 44 and 126 is too open.
Answer:
Step-by-step explanation:
lets pick 2 points on the line....(6,5) and (10,3)
slope = (y2 - y1) / (x2 - x1)
(6,5)....x1 = 6 and y1 = 5
(10,3)....x2 = 10 and y2 = 3
now we sub
slope = (3 - 5) / (10 - 6) = -2/4 = -1/2
now we use y = mx + b
slope(m) = -1/2
u can use either of ur points...I will use (6,5)...x = 6 and y = 5
now we sub and find b, the y int
5 = -1/2(6) + b
5 = -3 + b
5 + 3 = b
8 = b
so ur equation is : y = -1/2x + 8 <===
By Pythagoras Theorem,
the length of the other leg= (12^2-9^2)^1/2
hope this helps
