Y varies directly as x. If y=300 when x=20 find Y when x=7

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
