Answer:
(2, 3)
Step-by-step explanation:
because the triangle moved 2 times to the right (x) and 3 times higher (y)
when two is added to two the result is 4 !!
2+2=4 !!!
2(x+4x)-4=4(x-3)+2(x+10)
2x+8x-4=4x-9+2x+20
10x-4=6x+11
10x=6x+15
4x=15
x=3.75
7x = 10
•Paula added 7 to 10, which was her mistake. To fix her mistake, she would have to divide by 7, instead of adding 7. The correct answer is 10/7.
20C0 - 20C1 + 20C2 - 20C3 + . . . + 20C10 = 1 - 20 + 190 - 1,140 + 4,845 - 15,504 + 38,760 - 77,520 + 125,970 - 167,960 + 184,756 = 92,378
