Answer:
A. (4, 12)
Step-by-step explanation:
Adding the second equation to twice the first will eliminate y.
2(10x +2y) +(3x -4y) = 2(64) +(-36)
23x = 92 . . . . . . . . simplify
x = 4 . . . . . . . . . divide by 23
This value matches choice A: (4, 12).
I hope this helps you
100-y=x^2.
x= square root of 100-y
y^-1= square root of 100-x
The answer is 5r^2 -1
