PLEASEEE HELP, ITS A SUMMATIVE Topic is quadratics
It is raining heavily and traffic police have been monitoring a local highway. According to their records the length of the highway id 4.63km. They observe that at any one time there are 50 cars traveling in one direction on the highway. At what speed should the cars be traveling in order to avoid not hitting the car in front, should they need to stop immediately?

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the two may have that, even a breakdown is probably offered

5+2x=a

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
