to find a percent you have to find a equivalent fraction that equals to ___\100
The probability of getting a factor of 12 on a fair dice is 5/6 or approximately 83%.
Xy=130
y=3+x
x(3+x)=130
x²+3x-130=0
(x+13)(x-10)=0
x= -13 or 10
since the question says X and Y are positive we just dismiss-13
x=10
and y=13
Next time, please begin with a question of your own, and share whatever work you have done.
Look at the illustration. You want to reflect point J in the origin. Point J's coordinates are (0,3). If you reflect this point in the origin, you'll get the new point J' as (0,-3).
Next, reflect point I in the origin. The original point I is (-4,4). Reflecting this in the origin takes you from Quadrant 2 to Quadrant 4. The coordinates of the new point I' are (4,-4). Spend enuf time with this so that it becomes clear.
Next, reflect point K in the origin. You might want to draw a straight line thru point K and the origin. The new point, K', will lie on this line the same distance from the origin as is the old point K is from the origin.
