If f(x) is parallel to the line y 2x+, which function could be f(x)?
O Rx)=2x+9
4
o RX)=-3x+9
o RX)= 9x+
2
Of(x)= 9x-
5
2

Step-by-step explanation:

The line y = 2x + c

has a slope of 2.  Any new line parallel to this one must also have a slope of 2.

Correct choices include the first one alone.  None of the others are correct.  

360/29

step-by-step explanation:

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
