Answer:

It is a solution

Step-by-step explanation:

8d+6= -8d-186

Add 8d to each side

8d+8d+6= -8d+8d-186

16d +6 = -186

Subtract 6 from each side

16d +6-6 = -186 -6

16d = -192

Divide each side by 16

16d/16 = -192/16

d = -12

2. Richmond Appliance repairs washing machines. The revenue that the company earns is given by the function R(h) = 20 + 45h doll

Vesnalui [34]

The number of hours needed for the company to break even happens when
$R(h)=C(h)$

$20+45h= 5h^{2}-30$ , rearranging to make the equation 'zero' on LHS
$0= 5h^{2}-30-20-45h$
$0= 5h^{2}-45h-50$ , divide each term by 5
$0= h^{2}-9h-10$ , factorise
$0=(h+1)(h-10)$ , equate each factor to zero
$h=-1$ and $h=10$

We choose the positive value of $h$

Hence, the number of hours needed to break even is $h=10$
