(2,-3)
x1+x2/2 , y1+y2/2
-6+2/2 , -2-4/2
4/2, -6/2
2,-3
The answer is therefore (2,-3)
Answer:
Jackie: 11
Paula: 19
Step-by-step explanation:
11+19 = 30
9x^2 -c =d
add c to each side
9x^2 = c+d
divide by 9
x^2=(c+d)/9
take the square root on each side
x = +- sqrt ((c+d)/9)
simplify
x = +- 1/3 sqrt (c+d)
Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)
