Answer:
D' = (5, 2)
Step-by-step explanation:
Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.
You would use the pythagorean theorem to solve this equation: a^2 + b^2 = c^2
12^2 + b^2 = 20^2
b^2 = 16
x = 16
The point-slope form if the coordinates are (-1,1) and (1,-1)
y = ax + b = ( - 1 )x + b = - x + b < i guess>
Ok done. Thank to me :>
So your TOTAL number is 30, and they're saying only 5/6 of that TOTAL number showed up. So by a simply multiplication you'll find how many showed up:
30 x 5/6 = 25
Hello,
we suppos the numbers are 1 and 2.
1+2=3
67-3=64
We must thus add 32 to each number
numbers are 1+32=33
and 2+32=34
(we don't need equation to solve that!)
