The ratio is equivalent because 1/20 is 5 which means 9/10 is equal
let x and y be the two numbers respectively.
since there diff is 20 so
x-y=20....(1)
then they are in ratio 3:7 so
x/y=3/7
or x=3y/7....(2)
now putting the value of x in eqn (1) we get
3y/7-y=20
or 3y-7y=20×7
or -4y=140
or y=140/-4
y=-35
now keeping the value of y in eqn (2) we get
x=3×(-35)÷7
x=-15
therefore,the numbers are x=-15 and y=-35.
Answer:
slope= 0
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
m= (-4-1),(6-1)
subtract the x1 and y1 which is -1--1 equal to 0
now same goes for x2/y2 we subtract them
which we end up getting 10
but because we have 0 whatever number we get it doesn't matter because at the end our answer will end up being 0.
