Y=18
x=6
following since they vary directly it would be in
y=mx form
18=m(6)
6*3=18
your answer is y=3x
heyy thanks bro you too take care and stay safe!!!
Sqrt [(-4 -(-7)^2 + (6-3)^2 ]
= sqrt (9 + 9)
= sqrt 18
which can also be written as sqrt 9 * sqrt 2 = 3 sqrt 2

Answer:
2 numbers could be 10 and 12
or - 12 and - 10
Step-by-step explanation:
let the 2 numbers be x and x + 2
since they are 2 consecutive even numbers, the difference between them is 2
the difference between the reciprocals is 1/60
we have to mulitply the 2 denominators x and (x+2) to get a common denominator for the 2 fractions
=
we can then remove the brackets from the numerator and denominator
and then cross multiply
60 * 2 = x² + 2x
120 = x² + 2x
x² + 2x - 120 = 0
we have a quadratic equation which needs to be solved
x² + 12x - 10x - 120 = 0
x (x + 12) - 10(x + 12) = 0
(x - 10) (x + 12) = 0
x - 10 = 0 or x + 12 = 0
x = 10 x = -12
