25 - 16 / 2^3 - 5 + 3
Start off by putting 2 to the third power to get 8. Then divide 16 by 8 to get 2. 25-2=23-5=18+3=21
The slope is undefined because of the formula y2-y1/ x2-x1
in this case in (5,4) the 5 is x1 and the 4 is y1. in (5,8) the five is x2 and the 8 is y2. Pug the number in for the formula and you will see that it is D. undefined.
∠L = 180° - (∠M + ∠N) = 180° - (112° + 31°) = 180° - 143° = 37°
The slope of the line 5/7.
How do i know this?
Well the slope of a line is considered as rise/run.
So we start at the beginning and then go up until the line intersects a corner again. Then we mark that down.
Go back to the beginning and count how many times it takes to reach the height of the intersected corner. So it is 5.
Then we go to the right until we reach the point. And it takes 7 squares to reach it, so the slope it 5/7.
Your welcome! :D
