Question

Find the missing coordinate x or y for the indicated distance OF (x, 8) and (1, 8), d = 5

Answer 1

Answer:

$x = 6 \: \: \: \: \: \: \: or \: \: \: \: \: \: x = - 4.$

Step-by-step explanation:

$\sqrt{ {(x - 1)}^{2} + {(8 - 8)}^{2} } = 5 \\ \\ |x - 1| = 5 \\ \\ x - 1 = 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: x - 1 = - 5 \\ \\ x = 6 \: \: \: \: \: \: \: or \: \: \: \: \: \: x = - 4.$
