Can someone me solve 2√x−4=10 i'm confused.

let's analyze two cases

case A) 2(√x)−4=10
2√x=10+4> 2√x=14> √x=14/2> square---> x=7²> x=49

case B)
2√(x-4)=10
√(x-4)=10/2> square---> x-4=5²> x=25+4> x=29

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
