Use the Distance Formula to write an equation of the parabola. focus: (0.-7)
directrix: y = 7

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?

You need to solve a system of equations. you decide to use the elimination method. which of these is not allowed? 3x - 2y = 7 3x + 4y = 17 equation 1 equation 2

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
