Answer:
y = -3
Step-by-step explanation:
{y = x/2 - 4
y = 1 - 2 x
Substitute y = x/2 - 4 into the second equation:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
In the second equation, look to solve for x:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
Add 2 x + 4 to both sides:
{y = x/2 - 4
(5 x)/2 = 5
Multiply both sides by 2/5:
{y = x/2 - 4
x = 2
Substitute x = 2 into the first equation:
{y = -3
x = 2

The value of y when x= 2401 is -10
<h3>How to determine the value of x?</h3>
An inverse variation is represented as:
Where k is the proportionality constant
When y = -70, x = 49
So, we have:
Take the square root of 49
Multiply through by 7
k = -490
Substitute k = -490 in
When x =2401, we have
Evaluate the square root
Divide
y = -10
Hence, the value of y when x= 2401 is -10
