\sqrt(x^(2)-14x+49)=x-7

infinite solutions

Step-by-step explanation:

note the expression inside the radical is a perfect square, that is

x² - 14x + 49 = (x - 7)², then

= x - 7

= x- 7, that is

x - 7 = x - 7

Since both sides are the same then any value of x will make the equation true.

The equation has infinite solutions

Okay, lets g!

"There is a profit of $6,500 in January and $17,500 in May.
There are four months between January and May.
The rate of change= ($17,500 - $6,500) 4= $11,000/ 4= 2,750

So, the rate of change in profit is 2,750 per month."
