10^2 + 5^2 = Diagonal length. so, 100 + 25 = 125 diagonal length
Answer:
There is no way it can equal 360 since 60+120+150+75=405? Was it a typo?
Step-by-step explanation:
Okay, I know this looks intimidating but don't worry, it isn't that hard! All you need to do is take any two points on the line, we'll do (-3, 0) and (0,6), choose one to be x1 and y1, and then the other to be x2 and y2, it doesn't matter which one you decide to choose. We'll use (-3,0) as x1 and y1 then (0,6) as x2 and y2, now just use the formula, which is y2 - y1 / x2 - x1, to use this take y2(6) and y1(0) and subtract 6 - 0, which equals six. Then we'll use x2(0) - x1(-3) which equals 3, so now, you take y2 - y1 /x2 - x1 and turn it into 6/3, and you get two, hope this helped you!
If I'm reading your question correctly: "<span>F(x)=7x+9/8x-9 when -f(x)," then all you have to do to find -f(x) would be to put a negative sign in front of ALL
of 7x + 9 / (8x-9):
9
- f(x) = -7x - --------
8x-9</span>
2/3 + 1/5 = 4/5 + 1/5 = 1 so B is the answer
