Answer: the slope is the fraction value that a line goes up by written in rise over run form
Step-by-step explanation: for example, if a line has a slope of 1/1, that means it rises one unit, and moves right one unit. you can simply find slope by counting how many units a line rises, and goes over by to find your slope!
Answer:
-5r + 5
Step-by-step explanation:
We simply simplify by adding like terms. Only thing we can combine are the constants -5 and 10, which we get 5. So then our answer is -5r + 5.
Answer:

Step-by-step explanation:
10 * sqrt(81/25 * -1) = 10 sqrt(81/25) * sqrt(-1) = 10 *9/5 * i
I don't think this is possible.
The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3
And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0
Sorry but there is not an answer. :(
