Question

Find y if -19 x [ 4 +( -2 ) ] = -19 x 4 + ( -19 ) x y
answer fast please​

Answer 1

Answer:

$.$

Step-by-step explanation:

Since "y varies inversely as x" it means that y=k%2Fx where "k" is some fixed number.

y=k%2Fx Start with the given equation

25=k%2F4 Plug in x=4 and y=25

25%2A4=k Multiply both sides by 4

k=100 Multiply

-------------------

y=k%2Fx Go back to the given equation

y=100%2Fx Plug in k=100

10=100%2Fx Now plug in y=10. The goal now is to solve for x

10x=100 Multiply both sides by 'x'

x=100%2F10 Divide both sides by 10

x=10 Reduce
