Answer:
(42, 21) or (–42, –21)
Step-by-step explanation:
let A(x, y), A on line 2y = x
distance
x² + y² = 2205
(2y)² + y² = 2205
y² = 441
y = ±21
x = ±42
I think it is twelve as four timesed by three is twelve
Step-by-step explanation:
3x - 4(4) = 65
3x - 16 = 65
3x = 81
x = 27
Answer:
x = -10 and x = 9
Step-by-step explanation:
-x = 10 <- divide -1 on both sides: -1x / -1 and 10 / -1.. you get -10 = x
repeat with -x = -9 <- divide -1 on both sides: -1x / -1 and -9 / -1.. you get 9 = x
