Rearrange them to slope-intercept form

y = 7x + 2

y = -(1/7) x + 8

product of their slopes is  7 * -1/7  = -1  so they are perpendicular

Given the formula, all you have to do is input 10 into the places where there are x.
500*10-20*10^2
500*10-20*100
5000-2000
3000
So the profit is $3000! Hope this helped!

Answer: Equation Classification : A. Possible and Determined;  

B. Possible and undetermined and C.    Impossible:

Step-by-step explanation:

A. Possible and Determined: These are equations that admit at least one solution.

Example: 2x = 3 → x = <u>3 </u>

                                     2

B.   Possible and undetermined:

They are equations that have infinite solutions.

Example: x + 2 = x + 2 → The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.

C. Impossible: Has no solution.

Examples:

0x = 4 → Unable to divide 4 by 0.

y = y + 2 → y - y = + 2 → 0 = +2 → There is no equation without unknown.
