If a car travels 660 miles in 11hours what is the speed of the car?

*write the equation of the line given the following conditions

1. m=-2 y intercept:5

2.perpindicular to y=3x-1 containing the point (-3,7)

* determine whether the ordered pair is a solution to the system
1. 2x+y=3 (1,1)
x-2y=-1

2.4x+y=-4
-x-y=1 (-2,4)



*evaluate each function
f(x)=x^2-2x for x=3


f(x)=2x-1 for x=-10


PLEASE HELP ME....CAN YOU EXPLAIN HOW YOU GET THE ANSWER I REALLY NEED HELP
