Among the choices provided above the function best models the linear relationship is <span>y = 22,000x + 40,000</span>
So the way I would think of this is take off the negative from the 7 if it confuses you. So now which number is farther from zero 7 or 5. However assure that you put the negative back in your final answer
Answer is : -7
Option A
The values of x are 3.58 or 0.42
<u>Solution:</u>
Given, equation is
We have to solve for the x and choose from the options given,
Now, take the equation,
Negative sign cancels on both sides
Taking square root on both sides, we get
Hence, the values of x are 3.58 or 0.42, so option A is correct.
