Question

If y = 7x, what happens to x when y is increased by 5 times its original value?

A)
x decreases 5 times its original value
71
B)
x increases to
its original value
x also increases 5 times its original value
D)
x decrease to
of its original value

Answer 1

Correct option is C) x also increases 5 times .

Explanation:

Given:

y=7x

The above equation can be rewritten as

`x=(y)/(7)`

Now, if we increase the y 5 times then we would have,

`x'=5*(y)/(7)`

Which is also equal to

x'=5x

Hence we can say that if we increase the value of y 5 times then we get that the value of x also increases 5 times.

Answer 2

Answer: x also increases 5 times its original value
