Question

Write a pair of integers whose product is -36 and difference is 15.

l) You are at an elevation 380m above sea level as you start a motor ride. During the ride, your

elevation changes by the following metres: 540m, -260m,100m . What is your elevation

relative to the sea level at the end of the ride?​

Answer 1

Answer:

xy = -36

y= -36/x

x-y = 15

x-36/x = 15

x2- 12 -3x+36= 0

x2 -12y-3x +36=0

x=(x-12) -3(x-12=0

x=12 x=3

y=-3 y=-12
