The sketch shows part of a rollercoaster ride between 2 points A and B, at the same horizontal level. The highest point in this section C is 20 m above AB. The length of the ramp is 55 m and the length of the drop is 30 m. Find the horizontal distance between A and B.

10000

step-by-step explanation: divide by 2,

answer: -2+√x,-2-√x

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

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
