Answer:
Step-by-step explanation:
Let the two numbers be x and y
So we have:
using the elimination method, add the two equations together:
solve for x:
substitute our value for x back into the first equation we made:
therefore,
the answer is true because 6x multiply -2 to give -12x and 6x multiplies x² to give 6x³
If segment AB is perpendicular to segment CD, then a right angle (90°) is formed.
7x + 27 = 90
7x = 63
x = 9
Answer:
Step-by-step explanation:
d = 7%2F2
-2, -2+7%2F2, -2+2%287%2F2%29, -2+3%287%2F2%29, 12
-2, -4%2F2+7%2F2, -4%2F2+14%2F2, --4%2F2+21%2F2, 12
-2, 3%2F2, 10%2F2, 17%2F2, 12
-2, 3%2F2, 5, 17%2F2, 12
