Question

Need some help, kinda difficult

Answer 1

Since y is directly proportional (direct proportion) to x, the value of x when y = -7.93 is equal to 1.3.

What is a direct proportion?

Mathematically, a direct proportion is also referred to as direct variation and it can be represented with the following mathematical expression:

y = kx

Where:

• y and x are the variables.
• k represents the constant of proportionality.

Since y varies directly (direct proportion) with x, the variable x and y must remain in a constant ratio.

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 12.2/-2

Constant of proportionality (k) = -6.1

Now, we can determine the new value of x as follows:

k = y/x

x = y/k

x = -7.93/-6.1

x = 1.3
