Answer:
y = x
Step-by-step explanation:
line has a slope 1 and passes through the origin . So the equation is y = x
To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

Now square root both sides to get

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

and
Let the original price of headphone = x
there is 40% discount which is 0.40x
so the payment price will be x-0.40x = 0.60x
Given that paid amount is $36
so both will be equal
0.60x = 36
x=36/0.60
x=60
Hence final answer is $60.
Domain is X and Range is Y. So the range will be all the Y's which is the second answer
