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

x also increases 5 times its original value

Step-by-step explanation:

Correct option is C) x also increases 5 times .

Step-by-step explanation:

Given:

y=7x

The above equation  can be rewritten as  

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

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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
